About the Volume Manager (VxVM) component in a Virtual I/O server
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.
