3. Change primary boot path back to current boot device:

# setboot -p device_path_from_above

(Use -a if you want to change the alternate bootpath.)

Removing a Mirrored Volume Manager Root Disk

Use the following commands to remove the mirrored Volume Manager Root Disk:

# daname=<c#t#d#> /* of mirrored root disk */

# dmname=`vxprint -g rootdg -F %dmname -e sd_da_name~/$daname/|head -1`

# plxnames=`vxprint -g dg -F "%assoc" -e sd_dm_name==\"$dmname\"`

# vxplex -o rm dis $plxnames

# vxdg -g rootdg rmdisk $dmname

Adding Swap Space Using VxVM Volumes

The HP System Administration Manager (SAM) currently does not have the capability to

add swap space using VxVM volumes. You need to use the VxVM CLI; for example:

1. Run the command:

# /etc/vx/bin/vxdisksetup -i device

2. If this command comes back with:

vxvm:vxdisk: ERROR: Device device is already in use by LVM.

then, go to Step 3; otherwise, go to Step 4.

3. Run the following commands (it is necessary to run pvcreate ﬁrst, since

/etc/lvmtab may not exist):

# pvcreate -f /dev/rdsk/ device

# pvremove /dev/rdsk/ device

# vxdctl enable

# /etc/vx/bin/vxdisksetup -i device

4. Run the following commands:

# vxdg adddisk swapdisk=device

# vxprint swapdisk

Disk group: rootdg
