vgcreate command failed & server hanged.....

SUBRATAhp-unix — Thu, 21 Oct 2010 09:38:09 GMT

Hi,

I was creating a new VG with a san disk...While i have given the command below it got hanged and after going through console login i found the server was crash dumping.

# vgcreate -p 150 -l 100 -s 32 -e 3264 /dev/vgedc_d731_d /dev/dsk/c194t0d3

here I would like to mention the hp-ux version my PA-RISC server is having is hp-11.00..

I promise for good points...

I don't think the vgcreate command alone could crash the server. Something else may have gone wrong. Either totally unrelated to the vgcreate or having to do with the SAN access / FC interface.

You have to look at the crash dump to get more details.

can you post ioscan -funC disk output.
check the syslog, dmesg. any error you see on the console?
what type or model of san are you using ?

>>same thing happend a few years earlier with the same version of hp-unix i.e hp-ux 11.00..

and what was done that time to recover the crashed system.

The system is up now, only problem i faced was the /etc/lvmtab got corrupted and all the vg's except root vg were not getting activated i had copied the backup lvmtab and activated the vg's manually.. it is working fine.

Now my concern is whether it will be same thing happen if i proceed for creating the VG that is yet to be created in that server?

Do you have a support contract for this server? If so, get HP to analyze the crash dump. After that they will be able to tell you exactly what caused the crash.

if you could able to provide below input we may able light on your problem.

a)strings /etc/lvmtab

b)vgdisplay -v

c)more /etc/rc.log

d)syslog and oldsyslog

When was the last time you brought the system up to date on patches? Most crashes can be prevented with appropriate patches.
