LVMTAB PROBLEMS

[Kwahae_1]

Admins,

Getting the following after rebooting machine - which is also preventing creation of ignite tape:

Other than that, system is running fine.

How to clear up problem so that warning messages are eliminated and ignite tape can be completed successfully.

This system is on 11.23 rp5470

Will summarize.

Note that the c9 and c11 disks are no longer there. How can I remove them from the configs?

Best regards,

hi;
if you want to rebuild lvmtab ,you may use vgscan.
from then man page;
The vgscan command allows the re-creation of the /etc/lvmtab file and
possibly the associated volume group device files. This command
should be run only in the event of a catastrophic error such as the
deletion of the /etc/lvmtab file or the mismatch of names of the
physical volumes in the /etc/lvmtab file to the actual physical volume
path configuration. If the /etc/lvmtab file exists, the information
contained in the file is used to assist in rebuilding the file, but
the existing file is updated with the new corrected configuration.


#vgscan -a -v



regards,
mustafa

Hi Fabio,

Attached is the lvdisplay output.

Thanks

If they are truly gone, you can do:

# vgreduce -f /dev/vgapps

To remove the non-existant disks.

[Kwahae_1]

vgreduce -f /dev/vgapps

skip alternate link /dev/dsk/c7t0d2
vgreduce: Couldn't query physical volume "/dev/dsk/c9t0d2":
The specified path does not correspond to physical volume attached to
this volume group
vgreduce: Couldn't query physical volume "/dev/dsk/c11t0d2":
The specified path does not correspond to physical volume attached to
this volume group

need to move /etc/lvmtab to /etc/lvmtab.old

execute vgscan -p ( preview mode ) first then recreate with vgscan.

Read the man page.

Renamed lvmtab and run vgscan -a -v. Solved the problem and my Ignite is working like snake oil.

Thanks all.
