Remove a disk for replacement
Menu: VolumeManager/Disk/RemoveForReplace

Use this menu operation to remove a physical disk from a disk
group, while retaining the disk name. This changes the state
for the disk name to a "removed" disk. If there are any
initialized disks that are not part of a disk group, you will be
given the option of using one of these disks as a replacement.

Enter disk name [,list,q,?] list

Disk group: rootdg

DM NAME DEVICE TYPE PRIVLEN PUBLEN STATE

dm rootdisk01 c0t1d0 simple 1024 4188096 -
dm rootdisk02 c0t2d0 simple 1024 4188096 -

Enter disk name [,list,q,?] rootdisk01

The following volumes will lose mirrors as a result of this
operation:

rootvol standvol swapvol

No data on these volumes will be lost.

The following devices are available as replacements:

c0t3d0

You can choose one of these disks now, to replace rootdisk01.
Select "none" if you do not wish to select a replacement disk.

Choose a device, or select "none"
[,none,q,?] (default: c0t3d0) none


The requested operation is to remove disk rootdisk01 from disk group
rootdg. The disk name will be kept, along with any volumes using
the disk, allowing replacement of the disk.

Select "Replace a failed or removed disk" from the main menu
when you wish to replace the disk.

Continue with operation? [y,n,q,?] (default: y) y

Removal of disk rootdisk01 completed successfully.

Remove another disk? [y,n,q,?] (default: n) n


2. Rescan the devices and initialize the replaced disk:

# vxdctl enable
# /etc/vx/bin/vxdiskunsetup -C

For VxVM 3.5 on HP-UX 11iv1:

# /etc/vx/bin/vxdisksetup -iB

For VxVM 4.1/5.0 on HP-UX 11iv2 and 11iv3:

# /etc/vx/bin/vxdisksetup -iB format=hpdisk


Note: The -B option is necessary to initialize the bootable Veritas Volume Manager (VxVM) disk. Refer to thevxdisksetup man page for details

Replace a failed or removed disk
Menu: VolumeManager/Disk/ReplaceDisk

Use this menu operation to specify a replacement disk for a disk
that you removed with the "Remove a disk for replacement" menu
operation, or that failed during use. You will be prompted for
a disk name to replace and a disk device to use as a replacement.
You can choose an uninitialized disk, in which case the disk will
be initialized, or you can choose a disk that you have already
initialized using the Add or initialize a disk menu operation.

Select a removed or failed disk [,list,q,?] list

Disk group: rootdg

DM NAME DEVICE TYPE PRIVLEN PUBLEN STATE

dm rootdisk01 - - - - REMOVED

Select a removed or failed disk [,list,q,?] rootdisk01

The following devices are available as replacements:

c0t1d0 c0t3d0

You can choose one of these disks to replace rootdisk01.
Choose "none" to initialize another disk to replace rootdisk01.

Choose a device, or select "none"
[,none,q,?] (default: c0t1d0) c0t1d0

The requested operation is to use the initialized device c0t1d0
to replace the removed or failed disk rootdisk01 in disk group rootdg.

Continue with operation? [y,n,q,?] (default: y) y

Use a default private region length for the disk?
[y,n,q,?] (default: y) y

Replacement of disk rootdisk01 in group rootdg with disk device
c0t1d0 completed successfully.

Replace another disk? [y,n,q,?] (default: n) n

sd rootdisk02-02 swapvol-02 rootdisk02 204800 524288 0 c0t2d0 ENA


5. Verify the Logical Interchange Format (LIF) and Volume Manager label information on the replaced disk:

# lifls -l /dev/rdsk/c0t1d0
lifls: Can't list /dev/rdsk/c0t1d0; not a LIF volume

# vxvmboot -v /dev/rdsk/c0t1d0
vxvmboot: Disk /dev/rdsk/c0t1d0 does not contain a valid LIF volume.


6. Write Volume Manager volume information to the LABEL file:

# /opt/VRTS/bin/vxbootsetup rootdisk01


7. Display the LIF and Volume Manager label information:

# vxvmboot -v /dev/rdsk/c0t1d0

RENAMING A LOGICAL VOLUME

Step 1: Identify the Logical Volume that needs to be changed

# vgdisplay -v /dev/vg01 | grep "LV Name"

LV Name /dev/vg01/lvol01

# bdf /dev/vg01/lvol01

Filesystem kbytes used avail %used Mounted on

/dev/vg01/lvol01 102400 1133 94945 1% /opt/test

# umount /opt/test

# ll /dev/vg01

total 0

crw------- 1 root sys 64 0x010000 Nov 5 12:18 group

brw------- 1 root sys 64 0x010001 Nov 5 12:19 lvol01

crw------- 1 root sys 64 0x010001 Nov 5 12:19 rlvol01

# cd /dev/vg01

# mv lvol01 lvol01_renamed

# mv rlvol01 rlvol01_renamed

# vgdisplay -v /dev/vg01 | grep "LV Name"

LV Name /dev/vg01_renamed/lvol01_renamed

VGEXPORT & VGIMPORT

Following example shows, how vgexport/vgimport can be used to change the Volume Group Names

# bdf /opt/test

Filesystem kbytes used avail %used Mounted on

/dev/vg01/lvol01 102400 1133 94945 1% /opt/test

# umount /opt/test

Step 1: Create a mapfile in the preview mode

# vgexport -p -v -s -m /tmp/vg01.map /dev/vg01

Beginning the export process on Volume Group "/dev/vg01".

Volume group "/dev/vg01" is still active.

/dev/dsk/c0t9d0

# vgchange -a n /dev/vg01

Volume group "/dev/vg01" has been successfully changed.

Step 2: Export the Volume Group

# vgexport /dev/vg01

# ll /dev/*/group

crw-r----- 1 root sys 64 0x000000 Oct 31 13:15 /dev/vg00/group

# mkdir /dev/vg01_renamed

# mknod /dev/vg01_renamed/group c 64 0x010000

Step 2: Import the Volume Group with a new name

# vgimport -v -s -m /tmp/vg01.map /dev/vg01_renamed

Beginning the import process on Volume Group "/dev/vg01_renamed".

Logical volume "/dev/vg01_renamed/lvol01" has been successfully created

with lv number 1.

Volume group "/dev/vg01_renamed" has been successfully created.

# vgchange -a y /dev/vg01_renamed

Activated volume group

Volume group "/dev/vg01_renamed" has been successfully changed.

# vgdisplay -v | grep "VG Name"

VG Name /dev/vg00

VG Name /dev/vg01_renamed

REMOVING A LOGICAL VOLUME

Step 1: Identify the Logical Volume(s) to remove

# bdf /opt/test

Filesystem kbytes used avail %used Mounted on

/dev/vg01/lvol01 102400 1133 94945 1% /opt/test

# umount /opt/test

# vgdisplay -v vg01 | grep "LV Name"

LV Name /dev/vg01/lvol01

# lvremove /dev/vg01/lvol01

The logical volume "/dev/vg01/lvol01" is not empty;

do you really want to delete the logical volume (y/n) : y

Logical volume "/dev/vg01/lvol01" has been successfully removed.

Volume Group configuration for /dev/vg01 has been saved in /etc/lvmconf/vg01.conf
