We have seen how to calculate the vxprint and vxdisk values manually in the last post.But in very busy work schedule, its very difficult to spend time for calculating those values.I have developed the bash shell script(works for solaris) which will give you the volume size ,plex size,Disk size and sub-disk size (GB’s) of specific diskgroup in seconds.Adding to that this script […]
How to calculate vxvm volume size and objects size
