Example: Adding a Disk

1. Physically attach the disk to the system. Make sure there are no SCSI ID conflicts.
2. Run cfgmgr to detect new device. Device will be installed as hdiskn, where n is some integer.
3. Run extendvg vgname hdiskn to add the disk to a VG named vgname.
4. To create a new filesystem on this VG, use crfs -v jfs -g vgname -A yes -a size=262144. (Note that the size parameter indicates the number of 512-byte blocks, so 262144 means 128MB.)
5. To add 128MB to an existing filesystem on this VG, use chfs -a size=+262144 /filesystem/name.
