where can i download technical documentation of the tru64 lsm, especially interfaces (cli/gui?), commands (volprint,...), examples and howtos (replacing a mirrored disk, ...).
Solved! Go to Solution.

Re: tru64 lsm
1. Remove the failed disk from the disk group retaining the media records thus
# voldg ├в g mydg ├в k rmdisk media_name
2. Remove the disk access record
# voldisk rm disk_access_name
3. Ensure you have replaced the physical disk !
4. Restore the original disklabel or initialize a new one for the replaced disk.
#disklabel ├в wr dsk?? disktype
5. Initialise the new disk for use with LSM
if you have the original disk label: -
# voldisk ├в f init dsk?? offset=16
if you did not have the disk label: -
# voldisksetup ├в i dsk?? nconfig=? nlogs=? privlength=??
e.g.
# voldisksetup ├в i dsk? nconfig=2 nlogs=2 privlength=1024
6. Associate the new disk to a disk media record/disk group
# voldg ├в g mydg ├в k adddisk media_name=disk_access_name
7. Recover(synchronise) the plexes in the diskgroup
# volrecover ├в g mydg -sb
Enjoy

Re: tru64 lsm
-----------------------------------------
Here is the readable version !!!!!
-----------------------------------------
To give you a head start, here is the command sequence I always use in replacing a LSM mirrored disk : -
1. Remove the failed disk from the disk group retaining the media records thus
# voldg -g mydg -k rmdisk media_name
2. Remove the disk access record
# voldisk rm disk_access_name
3. Ensure you have replaced the physical disk !
4. Restore the original disklabel or initialize a new one for the replaced disk.
#disklabel -wr dsk?? disktype
5. Initialise the new disk for use with LSM
if you have the original disk label: -
# voldisk -f init dsk?? offset=16
if you did not have the disk label: -
# voldisksetup -i dsk?? nconfig=? nlogs=? privlength=??
e.g.
# voldisksetup -i dsk? nconfig=2 nlogs=2 privlength=1024
6. Associate the new disk to a disk media record/disk group
# voldg -g mydg -k adddisk media_name=disk_access_name
7. Recover(synchronise) the plexes in the diskgroup
# volrecover -g mydg -sb
Enjoy

Re: tru64 lsm
Seems to be a nice doku!
@Ross Minkov:
Tru64 is 5.1 (don't know whether it's a or b)
@Gary Hansford:
Thank you for these details.
Is there something in Tru64 like HP-UX OnlineJFS for easy expanding of mounted filesystems?

Re: tru64 lsm
Yes, the AdvFS file system has an 'addvol' option to transparently grow 'domains'.
Hein.

Re: tru64 lsm
- Yes, if your storage is capable of on-line LUN expancion, the ADVFS can expand filedomain reziding on this LUN.
See man mount, around -extend option.
Unfortunately, AdvFs advansed utilities license required. And for 'addvol' too.

Failures have been detected by the Logical Storage Manager:
failed disks:
dsk1h
failed plexes:
rootvol-02
swapvol-02
vol-dsk0g-02
vol-dsk0h-02
This is, what I would do:
1. # volplex -g rootdg -o rm dis rootvol-02 swapvol-02 vol-dsk0g-02 vol-dsk0h-02
2. # voldg -g rootdg rmdisk dk1a dsk1b dsk1f dsk1g-AdvFS dsk1h
3. # voldisk rm dsk1a dsk1b dsk1f dsk1g dsk1h
4. === physical replacement ==
5. # hwmgr scan scsi
6. # hwmgr show scsi => New unused disk dskX
7. # dsfmgr -e dskX dsk1
8. # disklabel -rw dskX
9. # volrootmir -a dskX
Now some questions:
a) Seems that dsk1f is a dummy (length=0).
However, i think it must be removed in 2, ok?
b) In 2. i have to use the disk_media_names.
Is dsk1g-AdvFS correct?
c) Is there a nice command to find out
the physical disk for dsk1?
d) I feel that there will be problems,
if the replacement disk isn't new
and was used in another LSM system.
Is a previous format neccessary?
e) What about 7. ?
The new disk will not be dsk1?
Any comments are greately appreciated!
