CROSS-POSTED in LSM notes
I have searched and searched, but can't find answer.
PROBLEM:
UNIX 3.2g (all Patches)
ASE 13. (all patches)
Through a comedy of errors system B root disk and mirror was
trashed. The customer didn't have a valid backup.
We used a backup from system A and handcrafted the system.
All went well except "/,swap, and /usr" mirroring.
What we currently have is :
rz8 and rz35 (/ swap and /usr) are mirrored, but DON'T have
copies on thr rootdg config on them. We have rz10 (temporary disk)
in rootdg, and it has the only valid copy of config info.
I check system A and rz8 and rz35 are the only disks in
rootdg and both have copies of the config.
I have original rootdg descriptor file from old system.
I need to somehow write the config info to rz8 and rz35
and remove rz10.
I thought about "volmake" or "volprivutil", but I am
not sure how to proceed.

Hi Dick,
I got finally some time.
You should give us the result of "voldisk list rz8" and "voldisk list
rz25" such that we can verify that you have an LSM private area on both
disks even if this private area has no LSM config/log.
if you have an LSM private area, and if the mirroring of your volumes
rootvol, swapvol and uservol is ACTIVE, you can proceed like this:
1) voldg -k rmdisk rz8
2) voldg -k rmdisk rz8b
3) voldg -k rmdisk advfs_rz8g (the_disk_media_name_of_the_usr_disk)
4) voldisk rm rz8
5) voldisk rm rz8b
6) voldisk rm rz8g (the_disk_access_name_of_the_usr_disk)
7) voldisk -f init rz8
8) voldisk -f init rz8b type=nopriv
9) voldisk -f init rz8g type=nopriv
10) voldg -k adddisk rz8
11) voldg -k adddisk rz8b
12) voldg -k adddisk advfs_rz8g=rz8
13) volrecover -sb -g rootdg
14) Wait for the end of the mirror synchronization (Coffee break!)
15) Repeat the same process for rz25
16) voldctl add disk rz8
17) voldctl add disk rz25
18) voldctl rm disk rz10
19) voldg rmdisk rz10
20) voldisk rm rz10
You may have to modify this procedure to adapt the disk media name and
disk access name to your real configuration. Also, it can be usefull to
check that you have well a LSM config on the rz8 and rz25 disk after
the voldisk init.
This procedure is described in more details in the LSM notefile in a
note that I wrote ... But don't remember the number !!!
Manu.
