es45 root mirror problem

I have an es45/tru64 v5.1A system that was installed recently. The system was installed to dsk0 and the volrootmir -a was used to mirror to dsk1.
After a few days, dsk0a was shown as FAILED.
We removed the disk and started to remove the plexes and volumes using volplex -dis and voledit -f -r rm
We then hit a problem whereby we couldn't remove the swapvol-01 plex. We found another forum post about this and removed patch 1998 to work around this issue.
The problem now is that we are unable to re-mirror the disk. The new disk we inserted was seen as dsk4, rather than dsk0.
volprint shows the following:
# volprint -Aht
Disk group: rootdg

DG NAME NCONFIG NLOG MINORS GROUP-ID
DM NAME DEVICE TYPE PRIVLEN PUBLEN STATE
V NAME USETYPE KSTATE STATE LENGTH READPOL PREFPLEX
PL NAME VOLUME KSTATE STATE LENGTH LAYOUT NCOL/WID MODE
SD NAME PLEX DISK DISKOFFS LENGTH [COL/]OFF DEVICE MODE

dg rootdg default default 0 1223295187.1026.20750:10:26:17

sd dsk1g-01 usrvol-02 dsk1g-AdvFS 0 4300800 0 dsk1g ENA

The issue seems to be around root02 - surely this is on dsk1 and shouldn't be shown as NODEVICE?

Can anyone suggest how I fix this?

Thanks

Re: es45 root mirror problem

Hi,

I've not used LSM for a *long* time, however you should be able to get the new disk, back onto dsk0 using dsfmgr.

# dsfmgr -m dsk4 dsk0

Hope this helps,

Regards,

Rob

Re: es45 root mirror problem

hello Robert Sandham
if cann't dis plex,I would like to use other methods can be replaced.
eg
disklabel dsk0 > /tmp/dsk0.label
voldg -g rootdg -k rmdisk
voldisk -rm
replace field harddisk
disklabel -z dsk1
disklabel -wr dsk1
disklabel -R -r -t advfs dsk1 /tmp/dsk0.label SCSI
disklabel -sF dsk1a(a~g) unused
voldisk -g rootdg -f -n init dsk1a type=nopriv
....
voldisk -g rootdg -f -n init dsk1g type=nopriv
voldg -g rootdg -k adddisk dsk1a=dsk1a
....
disklabel -R -r -t advfs dsk1 /tmp/dsk0.label SCSI(This is a very important step)
volrecover -sb rootvol
....
i wanted to useful for you

Re: es45 root mirror problem

Just rename the disk by
dsgmgr -e dsk4 dsk0
then do
#volrootmir -a dsk4 &
this will take some time.

This should solve the issue.
