Hi,
I have a defect disk in an LSM mirrored configuration. rz0 and rz1 are
mirrored.
What are the commands required to replace the disk rz1 and add to the
mirroring.
The OS is V4.0F. The output from the commands
root_at_psw318:/>volprint -Aht
Disk group: rootdg

sd rz17-01 pl-02 35560000 0 35560000 rz17 rz17
Can I use the following commands, please to replace the disk. I use the
same
addresses(slot)
voldg -g rootdg -k rmdisk rz1
voldisk rm rz1
voldisksetup -i rz1 privlen=1024 nconfig=1 nlogs=1 after changing and
labelling
the disk. I need the
whole disk
for mirroring.
voldg -g rootdg -k adddisk rz1=rz1
volrecover -sb rz1
rz0 and rz1 are mirrored. Disklabel -r rz0 gives the following output:

How to replace a failed
LSM mirrored system disk
SIBEC 15.Apr.1998
Operating Systems :
Digital UNIX V4.0x
Problem :
How to replace a failed LSM mirrored system disk
Solution :
1.) List the LSM configuration
# volprint -Aht
1.) Disassociate ALL plexes linked to the failed disk
e.g.
assume disk rz2 failed
# volplex -o rm dis rootvol-02
# volplex -o rm dis swapvol-02
# volplex -o rm dis usrvol-02
...
2.) Remove the failed disks from the disk group
# voldg -k rmdisk rz2a rz2b rz2g
# voldisk rm rz2a rz2b rz2g
3.) now physically replace the disk rz2
4.) Write a disklabel onto the new disk (e.g. for a rz28 disk type)
# disklabel -rw rz2 rz28
5.) Add the disk to LSM again
# voldiskadd rz2
6.) Mirror the system disk again
# volrootmir -a rz2
