Reallocating disk space with HP-UX Volume Manager

[beardedbubba]

I have a server running HPUX B.11.23 and I am using HP Volume Manager. The disk space is being provided by an IBM SAN and the server is running IBM's SMclient.jar

I have volume group named /dev/vgsan100 with what appears to be three logical volumes: common, lun1, and lun4; see table below.

I have two questions: Am I correct in assuming that lun1 and lun4 are actually LUs that are separate from common and they are not a part of common? If these are separate LUs, how can I reallocate the space from lun1 and lun4 to common?


Physical Disk Logical volume Use Mbytes Mount Point

/dev/dsk/c17t0d5 /dev/vgsan100/common VxFS 102368 /common
/dev/dsk/c14t0d6 /dev/vgsan100/common VxFS 102368 /common
/dev/dsk/c14t0d0 /dev/vgsan100/lun1 Unused 102368 [none]
/dev/dsk/c17t0d3 /dev/vgsan100/lun4 Unused 102368 [none]

luns 1 and 4 are separate from common, yes.

You could remove the logical volumes on these luns (lvremove command), and then extend (lvextend command) the common logical volume by adding these luns into it.
