Volume Manager (VxVM) is a component of Veritas InfoScale whose functionality is disabled in Virtual I/O server (VIOS). VxVM commands that manage volumes or disk groups are disabled in the VIO server.

In the VIOS, VxVM does not detect disk format information, so the disk status for VxVM disks is shown as unknown. For example:

dmpvios1$ vxdisk list 
DEVICE           TYPE     DISK    GROUP   STATUS 
disk_0           auto     -       -       unknown 
ibm_ds8x000_02c1 auto     -       -       unknown 
ibm_ds8x000_0288 auto     -       -       unknown 
ibm_ds8x000_029a auto     -       -       unknown 
ibm_ds8x000_0292 auto     -       -       unknown 
ibm_ds8x000_0293 auto     -       -       unknown 
ibm_ds8x000_0337 auto     -       -       unknown

In the VIOS, VxVM displays an error if you run a command that is disabled, as follows:

dmpvios1$ vxdisk -f init ibm_ds8x000_0288 
VxVM vxdisk ERROR V-5-1-5433 Device ibm_ds8x000_0288: init failed: 
Operation not allowed. VxVM is disabled.

dmpvios1$ vxdg import datadg 
VxVM vxdg ERROR V-5-1-10978 Disk group datadg: import failed: 
Operation not allowed. VxVM is disabled.
