I am currently working on an ES40 running Tru64 5.1 B. The issue I am having is that we have oracle installed and we have 4 directories. /u01 /u02 /u03 and /u04. 3 of these directories have been set up as domains such as oradata02 for the /u02 and on and on. The problem I am having is that recently /u04, or oradata04 began to disappear and then reappear. However, now in the past two weeks it has disappeared and I am unable to get it to mount. On reboots I get an error 5 panic message, and when I try to go through sysman and create the domain it tells me it can not get the partition size. Anyway, I am attaching an error to this and if anyone could help it would be greatly appreciated.
Thanks in advance,
Karsten J. Hilton

Re: Tru64 5.1 B Domain Missing
Considering it has come and gone you might want to re-seat it. Pop out, push in, try again.
You may want to pre-try the raw device with:
dd if=/dev/rdisk/dsk7c bs=8k count=1000 of=/dev/null
You might want or need to use the '/sbin/advfs/verify' and/or
/sbin/advfs/salvage to bring the AdvFS data to life.
But we have a communication problem here:
"directories have been set up as domains"
The above line does not compute
Domains live on one or more devices.
Only 1 domain per device
Domains contain one of more filesets.
Directories are used as mountpoint for filesets, not domains.
Issue the command:
ls -l /dev/fdmns/*
That should show you the mapping of domains and devices.
Next use showfsets on those domains.
If you continue to have problems with this, then please re-state your question with the above naming in mind.
Specifically it would be interesting to know whether u04 is the only fileset in a domain on dsk7 or not.
hth,
Hein.

Re: Tru64 5.1 B Domain Missing
No problem. You are trying. But the domain vs fileset situation is still not clear yet.
An other source of info for this is:
# grep /etc/fstab u0
>> have HSZ70 system with 6 raidsets.
Again an communication issue.
A 'raid set' is too generic.
I suspect it is a raid 5, but you need to confirm that for yourself: Raid-0, Raid-0+1 or Raid 5?
Anywhay.. you want to 'visit' that HSZ through it serial line interface or using hszterm over the scsi bus to find out what it thinks about the devices. What is up, what is down? HSZ> SHOW UNIT ... SHOW DISK...
Maybe that dsk7 re-appeared to Tru64 as an other disk after some fat fingering?
Chech with #hwmgr scan scsi followed by hwmgr show scsi. If need be triple check using the WWID's
>> It is that raidset or group of disks that seem to not be able to work right.
Right, so ask the HSZ for details.
It should know more than Tru64 can know.
Hein.

Call support, internal or external.

Consult the man pages.

Re: Tru64 5.1 B Domain Missing
There must be some problem with storage.
And post output of:
# disklabel -r dsk7
Some other things:
/u04 is mount point for file system
/dev/disk/dsk7c is disk device file
oradata04 is advfs domain name
Regards

Re: Tru64 5.1 B Domain Missing
Perhaps you have already done this or been directed. From your error file:
Type of operation: Read
Error: 5 (see /usr/include/errno.h)
So,
$ grep 5 /usr/include/errno.h
#define EIO 5 /* I/O error */
You probably have a hardware error on the physical device as "presented" to the system by the controller. Whether you or someone else has configured JBOD, RAID 1 or RAID 5 device on the controller is another level of discovery. Perhaps the controller has, as someone else suggested, lost contact and the physical disk(s) is/are O.K.
The cause of the read error may allow you not to have to restore the device from backup tapes, but I would guess it's unlikely. Here's hoping you have done level 0 backups in the recent past.
Looking to recovering Oracle, consult with your DBA as the interrelationships among files may cause Oracle not to start properly with out-of-sync databases, config files, tablespaces that are stored on other devices. The entire Oracle config may have to be restored across all disks to a point in time where all of the files are coherent.
Best of luck. ,,, Joe S.
