ibrix_vg

Creates, extends, reduces, or deletes volume groups.

Description

Use ibrix_vg to perform these tasks:

• Create volume groups from discovered physical volumes. This is the second step in the manual

method of creating a file system.

• Extend or reducing a volume group by adding or removing physical volumes.

• Delete unneeded volume groups. Before deleting a volume group, first delete the logical

volumes (segments) created from it.

• List information about volume groups.

Synopsis

Create a volume group:

ibrix_vg -c -g VGNAME -p PVLIST

The command creates volume group VGNAME from the physical volumes in PVLIST. For example,

the following command creates volume group ivg1 from physical volumes d1, d2, and d3:

<installdirectory>/bin/ibrix_vg -c -g ivg1 -p d[1-3]

Extend a volume group:

ibrix_vg -e -g VGNAME -p PVLIST

The command extends volume group VGNAME with the physical volumes in PVLIST.

Remove physical volumes from a volume group:

ibrix_vg -r -g VGNAME -p PVLIST

The command reduces volume group VGNAME by removing the physical volumes in PVLIST.

List volume groups for file serving nodes:

ibrix_vg -l [-h HOSTLIST]

Use the HOSTLIST option to limit the output to specific nodes.

List size and utilization information for volume groups:

ibrix_vg -l [-g VGLIST]

Use the VGLIST option to limit the output to specific volume groups.

List volume group information:

ibrix_vg -i [-g VGLIST]

For all volume groups or the groups specified in VGLIST, the command lists size and utilization

information, the physical volumes used to create the groups, the logical volumes (segments) built

on the groups, and the file serving nodes that can access the groups.

Delete volume groups:

ibrix_vg -d -g VGLIST

Back up the vgconfig maps on the Fusion Manager:

ibrix_vg -b -g VGLIST
