Disk Media State’s |
|
STATE’s |
Description |
| FAILING | Disk media is failing. |
| LFAILED | The node does not have local access to the disk. The node is sending private region I/Os through the network to a remote node that has local access to the disk. |
| LMISSING | The disk was not discovered locally by DMP. The node does not have a corresponding DMP device for the disk. |
| LOCAL_FAILING | Disk is fenced off. |
| NODEVICE | Disk is not valid. |
| NOHOTUSE | Disk cannot be used for Hot Relocation. |
| REMOVED | Disk is being removed from disk group. |
| RESERVED | Disk is reserved. |
| SPARE | Disk is marked as a spare for disk group. |
| ST_SPARE | Disk is marked as spare for storage pool. |
| VOLATILE | Disk state is changing. |
Volume States |
|
State |
Description |
| CLEAN | The volume is not started (kernel state is DISABLED) and its plexes are synchronized. For a RAID-5 volume, its plex stripes are consistent and its parity is good. |
| ACTIVE | The volume has been started (kernel state is currently ENABLED) |
| EMPTY | The volume contents are not initialized. The kernel state is always DISABLED when the volume is EMPTY. |
| INVALID | The contents of an instant snapshot volume no longer represent a true point-in-time image of the original volume. |
| NEEDSYNC | The volume requires a resynchronization operation the next time it is started. For a RAID-5 volume, a parity resynchronization operation is required. |
| REPLAY | The volume is in a transient state as part of a log replay. A log replay occurs when it becomes necessary to use logged parity and data. This state is only applied to RAID-5 volumes. |
| SYNC | The volume is either in read-writeback recovery mode (kernel state is currently ENABLED) or was in read-writeback mode when the machine was rebooted (kernel state is DISABLED). |
Volume Kernel States |
|
| State |
Description |
| DETACHED | Maintenance is being performed on the volume. The volume cannot be read from or written to, but certain plex operations and ioctl function calls are accepted. |
| DISABLED | The volume is offline and cannot be accessed. |
| ENABLED | The volume is online and can be read from or written to. |
Plex States |
|
State |
Description |
| ACTIVE | 1. When the volume is started and the plex fully participates in normal volume I/O 2. When the volume is stopped as a result of a system crash and the plex is ACTIVE at the moment of the crash |
| CLEAN | When it is known to contain a consistent copy (mirror) of the volume contents and an operation has disabled the volume. As a result, when all plexes of a volume are clean, no action is required to guarantee that the plexes are identical when that volume is started. |
| DCOSNP | Data change object (DCO) plex attached to a volume can be used by a snapshot plex to create a DCO volume during a snapshot operation. |
| EMPTY | Volume creation sets all plexes associated with the volume to the EMPTY state to indicate that the plex is not yet initialized. |
| IOFAIL | When the vxconfigd daemon detects an uncorrectable I/O failure on an ACTIVE plex, it places the plex in the IOFAIL state to exclude it from the recovery selection process at volume start time. |
| LOG | The state of a dirty region logging (DRL) or RAID-5 log plex is always set to LOG. |
| OFFLINE | The vxmend off task indefinitely detaches a plex from a volume by setting the plex state to OFFLINE. |
| SNAPATT | A snapshot plex that is being attached by the snapstart operation, when the attach is complete, the state for the plex is changed to SNAPDONE. If the system fails before the attach completes, the plex and all of its subdisks are removed. |
| SNAPDIS | A snapshot plex that is fully attached. If the system fails before the attach completes, the plex is dissociated from the volume. |
| SNAPDONE | A snapshot plex is ready for a snapshot to be taken |
| SNAPTMP | The SNAPTMP plex state is used during a vxassist snapstart operation when a snapshot is being prepared on a volume. |
| STALE | A plex does not have the complete and current volume contents, that plex is placed in the STALE state. Also, if an I/O error occurs on a plex, the kernel stops using and updating the contents of that plex, and the plex state is set to STALE. |
| TEMP | Setting a plex to the TEMP state eases some plex operations that cannot occur in a truly atomic fashion. |
Plex Kernel States |
|
State |
Description |
| DETACHED | Maintenance is being performed on the plex. |
| DISABLED | The plex is offline and cannot be accessed. |
| ENABLED | The plex is online. A write request to the volume is reflected in the plex. A read request from the volume is satisfied from the plex. |
SubCache & SubDisk Modes |
|
State |
Description |
| DET | The subdisk has been detached. |
| DIS | The subdisk is disabled. |
| dS | The subdisk in a RAID5 plex has failed and the RAID5 volume is in degraded mode (d indicates that the subdisk is detached, and S indicates that its contents are stale). |
| ENA | The subdisk is usable. |
| FAIL | The subdisk has been detached in the kernel due to an error. |
| NDEV | The media record on which the subdisk is defined has no associated access record. |
| RCOV | The subdisk is part of a RAID5 plex and has stale content. |
| RLOC | The subdisk has failed and is waiting to be relocated. |
| RMOV | The media record on which the subdisk is defined has been removed from its disk access record by a utility. |
SubVolume Modes |
|
State |
Description |
| ENA | The subvolume is usable. |
| DIS | The subvolume is disabled. |
| IOFAIL | The subvolume has been detached in the kernel due to an error. |
