Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

To remove a persistent dump volume
1
Run the following command to remove a VxVM volume that is being used as
a dump volume from the crash dump configuration:
#crashconf -ds /dev/vx/dsk/bootdg/dumpvol
In this example, the dump volume is named dumpvol in the boot disk group.
2
Display the new crash dump configuration:
#crashconf -v
You can now remove the volume if required.
Displaying disk information
Before you use a disk, you need to know if it has been initialized and placed under
VxVM control. You also need to know if the disk is part of a disk group, because
you cannot create volumes on a disk that is not part of a disk group. The vxdisk
list command displays device names for all recognized disks, the disk names,
the disk group names associated with each disk, and the status of each disk.
To display information on all disks that are known to VxVM
◆
Type the following command:
# vxdisk list
VxVM returns a display similar to the following:
DEVICE TYPE DISK GROUP STATUS
c0t0d0 auto:hpdisk mydg04 mydg online
c1t0d0 auto:hpdisk mydg03 mydg online
c1t1d0 auto:hpdisk - - online invalid
enc0_2 auto:hpdisk mydg02 mydg online
enc0_3 auto:hpdisk mydg05 mydg online
enc0_0 auto:hpdisk - - online
enc0_1 auto:hpdisk - - online thinrclm
The phrase online invalid in the STATUS line indicates that a disk has not
yet been added to VxVM control. These disks may or may not have been
initialized by VxVM previously. Disks that are listed as online are already
under VxVM control.
VxVM cannot access stale device entries in the /dev/disk and /dev/rdisk
directories. I/O cannot be performed to such devices, which are shown as
being in the error state.
