/usr/sbin/vxdiskadm – Menu-driven VERITAS Volume Manager disk administrator
The vxdiskadm command provides a menu-driven interface to perform common VERITAS Volume Manager (VxVM) disk administration tasks. The vxdiskadm script is interactive and prompts you for responses, supplying defaults where appropriate. Help is available at every prompt by entering a question mark (?) to display a context-sensitive help message.
Disks that Used in the Example:

Operations provided in the Volume Manager disk operations menu:
1. Add or Initialize one or more disks:
– Use this option to add disks to the system. The disks must already have been formatted and have a valid VTOC.
– Enter device address pattern list to initialize & add the disks to disk group. If the disk group is not configured already, it will be created.
– If a disk is found to already contain non-Volume Manager partitioning, you will be asked whether the disk should be encapsulated.
Example: Initializing all the disk’s which are connected to controller ‘C3’
Output: Select an operation to perform: 1 Add or initialize disks Menu: VolumeManager/Disk/AddDisks Use this operation to add one or more disks to a disk group. You can add the selected disks to an existing disk group or to a new disk group that will be created as a part of the operation. The selected disks may also be added to a disk group as spares. Or they may be added as nohotuses to be excluded from hot-relocation use. The selected disks may also be initialized without adding them to a disk group leaving the disks available for use as replacement disks. More than one disk or pattern may be entered at the prompt. Here are some disk selection examples: all: all disks c3 c4t2: all disks on both controller 3 and controller 4, target 2 c3t4d2: a single disk (in the c#t#d# naming scheme) xyz_0 : a single disk (in the enclosure based naming scheme) xyz_ : all disks on the enclosure whose name is xyz Select disk devices to add: [,all,list,q,?] list DEVICE DISK GROUP STATUS c3t1d0 - - online invalid c3t2d0 - - online invalid c3t3d0 - - online invalid c3t4d0 - - online invalid c3t5d0 - - online invalid c3t6d0 - - online invalid Select disk devices to add: [,all,list,q,?] c3 Here are the disks selected. Output format: [Device_Name] c3t1d0 c3t2d0 c3t3d0 c3t4d0 c3t5d0 c3t6d0 Continue operation? [y,n,q,?] (default: y) You can choose to add these disks to an existing disk group, a new disk group, or you can leave these disks available for use by future add or replacement operations. To create a new disk group, select a disk group name that does not yet exist. To leave the disks available for future use, specify a disk group name of "none". Which disk group [,none,list,q,?] (default: nodg) none Add site tag to disks? [y,n,q,?] (default: n) All disks will be initialized and left free for use as replacement disks. c3t1d0 c3t2d0 c3t3d0 c3t4d0 c3t5d0 c3t6d0 Continue with operation?

2. Encapsulate one or more disks
– Use this option to place one or more disks under Volume Manager control, that were added to the system before installing the Volume Manager.
– You will be required to reboot the system if any partitions are in use for mounted file systems or for running applications.
– You may have to modify application configuration files to use volumes, rather than direct disk devices, to access the disk partitions.
– File system mount information in /etc/vfstab will be adjusted automatically when the system restarted.
Example: Encapsulating Disk ‘c3t6d0’, which is having a solaris partition
Output: Select an operation to perform: 2 Encapsulate one or more disks Menu: VolumeManager/Disk/Encapsulate Use this operation to convert one or more disks to use the Volume Manager. This adds the disks to a disk group and replaces existing partitions with volumes. Disk encapsulation requires a reboot for the changes to take effect. More than one disk or pattern may be entered at the prompt. Here are some disk selection examples: all: all disks c3 c4t2: all disks on both controller 3 and controller 4, target 2 c3t4d2: a single disk (in the c#t#d# naming scheme) xyz_0 : a single disk (in the enclosure based naming scheme) xyz_ : all disks on the enclosure whose name is xyz Select disk devices to encapsulate: [,all,list,q,?] list DEVICE DISK GROUP STATUS c3t5d0 c3t5d0s2 testdg online c3t6d0 - - online c4t9d0 - - online invalid Select disk devices to encapsulate: [,all,list,q,?] c3t6d0 Here is the disk selected. Output format: [Device_Name] c3t6d0 Continue operation? [y,n,q,?] (default: y) You can choose to add this disk to an existing disk group or to a new disk group.

6. Mirror volumes on a disk
– Use this option to mirror a volume from one disk to another, by default if no destination disks specified any free disk in the disk group will be used.
– Mirroring volumes from the boot disk will produce a disk that can be used as an alternate boot disk.
Example: Mirroring the concat volume named ‘oravol’
v oravol - ENABLED ACTIVE 409600 SELECT - fsgen pl oravol-01 oravol ENABLED ACTIVE 409600 CONCAT - RW sd c3t1d0s2-01 oravol-01 c3t1d0s2 0 409600 0 c3t1d0 ENA
Output: Select an operation to perform: 6 Mirror volumes on a disk Menu: VolumeManager/Disk/Mirror This operation can be used to mirror volumes on a disk. These volumes can be be mirrored onto another disk or onto any available disk space. Volumes will not be mirrored if they are already mirrored. Also, volumes that are comprised of more than one subdisk will not be mirrored. Mirroring volumes from the boot disk will produce a disk that can be used as an alternate boot disk. At the prompt below, supply the name of the disk containing the volumes to be mirrored. Enter disk name [,list,q,?] list Disk group: oradg DM NAME DEVICE TYPE PRIVLEN PUBLEN STATE dm c3t1d0s2 c3t1d0s2 auto 65536 2031232 - dm c3t2d0s2 c3t2d0s2 auto 65536 2031232 - dm c3t3d0s2 c3t3d0s2 auto 65536 2031232 - dm c3t4d0s2 c3t4d0s2 auto 65536 2031232 - Enter disk name [,list,q,?] c3t1d0s2 You can choose to mirror volumes from disk c3t1d0s2 onto any available disk space, or you can choose to mirror onto a specific disk.

7. Move volumes from a disk
– Use this option to move any volumes that are using a disk onto other disks.
– Use this menu immediately prior to removing a disk, either permanently or for replacement.
Example: In mirror volume ‘oravol’ moving plex ‘oravol-02’ from the source disk ‘c3t2d0s2’ to the destination disk ‘c3t3d0s2’
v oravol - ENABLED ACTIVE 409600 SELECT - fsgen pl oravol-01 oravol ENABLED ACTIVE 409600 CONCAT - RW sd c3t1d0s2-01 oravol-01 c3t1d0s2 0 409600 0 c3t1d0 ENA pl oravol-02 oravol ENABLED ACTIVE 409600 CONCAT - RW sd c3t2d0s2-01 oravol-02 c3t2d0s2 0 409600 0 c3t2d0 ENA
Output: Select an operation to perform: 7 Move volumes from a disk Menu: VolumeManager/Disk/Evacuate Use this option to move any volumes that are using a disk onto other disks. Use this menu immediately prior to removing a disk, either permanently or for replacement. You can specify a list of disks to move volumes onto, or you can move the volumes to any available disk space in the same disk group. NOTE: Simply moving volumes off of a disk, without also removing the disk, does not prevent volumes from being moved onto the disk by future operations. For example, using two consecutive move operations may move volumes from the second disk to the first. Enter disk name [,list,q,?] list Disk group: oradg DM NAME DEVICE TYPE PRIVLEN PUBLEN STATE dm c3t1d0s2 c3t1d0s2 auto 65536 2031232 - dm c3t2d0s2 c3t2d0s2 auto 65536 2031232 - dm c3t3d0s2 c3t3d0s2 auto 65536 2031232 - dm c3t4d0s2 c3t4d0s2 auto 65536 2031232 - Enter disk name [,list,q,?] c3t2d0s2 VxVM INFO V-5-2-516 You can now specify a list of disks to move onto.

8 . Enable access to (import) a disk group
– Use this option to enable access by this system to a disk group.
– If you wish to move a disk group from one system to another, you must first disable (deport) it, on the original system. Then, move the disk between systems and enable (import) the disk group.
Example: Enabling access to import (Disks must be in online state)
Output: Select an operation to perform: 8 Enable access to (import) a disk group Menu: VolumeManager/Disk/ImportDiskGroup Use this operation to enable access to a disk group. This can be used as the final part of moving a disk group from one system to another. The first part of moving a disk group is to use the "Remove access to (deport) a disk group" operation on the original host. A disk group can be imported from another host that failed without first deporting the disk group. Be sure that all disks in the disk group are moved between hosts. If two hosts share a SCSI bus, be very careful to ensure that the other host really has failed or has deported the disk group. If two active hosts import a disk group at the same time, the disk group will be corrupted and will become unusable. Select disk group to import [,list,q,?] (default: list) list GROUP newdg (id: 1411552613.37.vxserver) DEVICES: c4t11d0 GROUP oradg (id: 1411553169.47.vxserver) DEVICES: c3t1d0 c3t2d0 c3t3d0 c3t4d0 Select disk group to import [,list,q,?] (default: list) oradg VxVM INFO V-5-2-374 The import of oradg was successful. Select another disk group? [y,n,q,?] (default: n)
9. Remove access to (deport) a disk group
– Use this option to disable access to a disk group that is currently enabled (imported) by this system.
– Deport a disk group if you intend to move the disks in a disk group to another system. Also, deport a disk group if you want to use all of the disks remaining in a disk group for some new purpose.
– For removable disk devices on some systems, it is important to disable all access to the disk before removing the disk.
Example: Disabling access to deport for the disgroup ‘oradg’
Output: Select an operation to perform: 9 Remove access to (deport) a disk group Menu: VolumeManager/Disk/DeportDiskGroup Use this option to remove access to a disk group that is currently enabled (imported) by this system. Deport a disk group if you intend to move the disks in a disk group to another system. Also, deport a disk group if you want to use all of the disks remaining in a disk group for some new purpose. You will be prompted for the name of a disk group. You will also be asked if the disks should be disabled (offlined). For removable disk devices on some systems, it is important to disable all access to the disk before removing the disk. Enter name of disk group [,list,q,?] (default: list) list GROUP DISK/VOLUME DEVICE/STATE LENGTH oradg disk c3t1d0s2 c3t1d0s2 2031232 oradg disk c3t2d0s2 c3t2d0s2 2031232 oradg disk c3t3d0s2 c3t3d0s2 2031232 oradg disk c3t4d0s2 c3t4d0s2 2031232 oradg volume oravol ENABLED 409600 Enter name of disk group [,list,q,?] (default: list) oradg VxVM INFO V-5-2-377 The requested operation is to disable access to the removable disk group named oradg. This disk group is stored on the following disks: c3t1d0s2 on device c3t1d0s2 c3t2d0s2 on device c3t2d0s2 c3t3d0s2 on device c3t3d0s2 c3t4d0s2 on device c3t4d0s2 You can choose to disable access to (also known as "offline") these disks. This may be necessary to prevent errors if you actually remove any of the disks from the system. Disable (offline) the indicated disks? [y,n,q,?] (default: n) y Continue with operation? [y,n,q,?] (default: y) VxVM INFO V-5-2-269 Removal of disk group oradg was successful. Disable another disk group? [y,n,q,?] (default: n)
10. Enable (online) a disk device
If you move a disk from one system to another during normal system operation, the Volume Manager will not recognize the disk automatically. Use this option to tell the Volume Manager to scan the disk to find what disk it is, and to determine if this disk is part of a disk group. Also, use this operation to re-enable access to a disk that was disabled by either the disk group deport operation or the disk device disable (offline) operation.
Example: Enabling off-lined or disabled disks
Output: Select an operation to perform: 10 Enable (online) a disk device Menu: VolumeManager/Disk/OnlineDisk Use this operation to enable access to a disk that was disabled with the "Disable (offline) a disk device" operation. You can also use this operation to re-scan a disk that may have been changed outside of the Volume Manager. For example, If a disk is shared between two systems, the Volume Manager running on the other system may have changed the disk. If so, you can use this operation to re-scan the disk. NOTE: Many vxdiskadm operations re-scan disks without user intervention. This will eliminate most needs to online a disk directly, except when the disk is directly offlined. Select a disk device to enable [,list,q,?] list DEVICE DISK GROUP STATUS c3t5d0 - - offline c3t6d0 - - online Select a disk device to enable [,list,q,?] c3t5d0 Enable another device?

11. Disable (offline) a disk device
Use this option to disable all access to a disk device through the Volume Manager. This operation can be applied only to disks that are not currently in a disk group. Use this operation if you intend to remove a disk from a system without rebooting.
[box type=”note” align=”alignleft” ]NOTE:Many systems do not support disks that can be removed from a system during normal operation. On such systems, the offline operation is seldom useful.[/box]
Example: Disabling a single disk which is not part of any disk group
Output: Select an operation to perform: 11 Disable (offline) a disk device Menu: VolumeManager/Disk/OfflineDisk Use this option to disable all access to a disk device by the Volume Manager. This operation can be applied only to disks that are not currently in a disk group. Use this operation if you intend to remove a disk from a system without rebooting. NOTE: Many systems do not support disks that can be removed from a system during normal operation. On such systems, the offline operation is seldom useful. Select a disk device to disable [,list,q,?] list DEVICE DISK GROUP STATUS c3t5d0 - - online c3t6d0 - - online Select a disk device to disable [,list,q,?] c3t5d0 Disable another device?
