3. Split the 2nd subdisk in to 2 each of 250 MB
bash-3.00# vxsd -g mohidg -s 250m split mohidg_d02 mohidg_d02 mohidg_d03

4. Create a new plex with the stripe layout using the splitted 2 subdisks ( record if any messages)
bash-3.00# vxmake -g mohidg plex mohidg_plex01 layout=stripe stwidth=32 ncolumn=2 sd=mohidg_d02,mohidg_d03

Volume commands:
1. Create a Volume of 1 GB bash-3.00# vxassist -g mohidg make mohi_vol02 1g
2. Extend the volume using vxresize by 1 GB
bash-3.00# vxresize -g mohidg mohi_vol02 1g
3. Reduce the Volume using vxassist by 500 MB
bash-3.00# vxassist -g mohidg shrinkby mohi_vol02 500m
VxVM vxassist ERROR V-5-1-7236 Shrinking a FSGEN or RAID5 usage type volume can result in loss of data. It is recommended to use the "vxresize" command or specify "-f" option to force the operation.
bash-3.00# vxassist -g mohidg -f shrinkby mohi_vol02 500m
4. Whats the difference in increase the size using vxresize and vxassist
vxassist requires a manual work to increase the Filesystem unlike vxresize which will automatically increase the file system.
Backup & Restore
1. Take a backup of newly created dg using vxconfigbackup command
# vxconfigbackup mohidg
2. Remove a disk and try to add new disk and restore the vxconfigrestore
# vxconfigrestore -p mohidg (Applied mode like preview)
# vxconfigrestore -d mohidg (Abort the applied mode restore)
# vxconfigrestore -c mohidg (Commit the applied mode restore)
Disk Encapsulation:
Will come soon........
