We can use the iostat command with the “-x” option to show VxVM device statistics:
iostat -x | grep VxVM |
The first column lists VxVMnnnnn where nnnnn is the minor number of the VxVM device. So we can use the following command to pull out the block device for this to understand which file system the statistic concerns:
find /dev/vx/dsk -type b -exec ls -l {} ;\ | awk '{print " ",$6,$10}' | grep " nnnnn " |
From this we can see the VxVM volume and disk group and relate these to the mounted file system and the VxVM disks/LUNs.
