AIX

Hi,

I'm working on AIX 5.2.0.0 and found something strange today. I found hd5 missing, and tried to create a new one, but failed.
Following are the commands issued and outputs. Is there any suggestion?

# lsvg -l rootvg
rootvg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
hd6 paging 16 16 1 open/syncd N/A

try running "synclvodm rootvg" and see if it fixes the LV information for you.

hmmm, hd5 is as per default the boot-volume. Losing it could be the last thing you ever saw of your system, so I suggest you make a mksysb AND a fullbackup real soon now.

After that, shut down and reinstall from scratch, you can use the mksysb you took to restore your configuration data to the rootvg: issue a "tctl .... fsf4" and read from there, it is a normal savevg file.

I know, "start over from scratch" is not a solution for your problem in the usual sense, but I suppose in a case where the configuration is heavily disrupted this is - in the long run - the best you can do.

Hope this helps.
