HP 3PAR Solaris Implementation Guide

Label the LUN:
format> label
4. Create and mount the file system. For example:
# newfs /dev/rdsk/c2t50002AC000010032d0s2
# mkdir /mnt/test
# mount /dev/dsk/c2t50002AC000010032d0s2 /mnt/test
5. Grow the LUN:
On the HP 3PAR StoreServ Storage, use the growvv command to grow the LUN. Increase
the LUN by 10 GB (for example):
# growvv <lun_name> 10G
6. Rescan the device tree on the host as shown above.
7. Use the luxadm command to verify the new LUN size. For example:
# luxadm display /dev/rdsk/c2t50002AC000010032d0s2
8. Unmount the file system and re-read the resized LUN:
# umount /mnt/test
# format
Select the LUN and then 'type':
format> type
Select '0' (Auto configure):
Specify disk type (enter its number)[2]: 0
Label the LUN:
format> label
NOTE: For Solaris x86, Auto configure under the type option in format does not
resize the LUN. Resizing can be achieved by selecting ‘other’ under the ‘type’ option and
manually entering the new LUN parameters, such as number of cylinders, heads, sectors, etc.
9. Re-mount and grow the file system:
# mount /dev/dsk/c2t50002AC000010032d0s2 /mnt/test
# growfs -M /mnt/test /dev/rdsk/c2t50002AC000010032d0s2
