Hi all,
We have a DL380 G5 server that run oracle 10g on RHEL4U0, and it accesses a
raid 1 harddsiks from the shared storage, before 2 days, when I tried
to list the directory that stored in the shared storage, system just hangs
out. After checking some stuff I noticed the following when I do fdisk for
the shared area partition:
Warning: Invalid flag 0X0000 of partition table 4 will be corrected by
w(rite) ....... Disk doesn't contain a valid partition table, but after
reboot I could access the directory and list all the contenets and I could
take a full backup. I saw also of mails talking about some HP acceselerator
error that the H/W engineer is analysing it.

Now, Is it H/W or OS related problem?

Regards
Mhm

You say the server "hangs" when accessing "shared storage".

What exactly does "shared storage" mean and how does the server acces it?

Is this Fibre-Channel or SCSI connected storage? And what driver are you
using? And what brand is it?

Also, most importantly, is the "shared storage" actually shared with
another server ?
