Save_config not responding

Shrikant Lavhate — Wed, 28 Nov 2007 08:36:12 GMT

Hi all,

There are lots of thread with same topic. I have gone through all but still can't get any solution hence troubling you with this new thread.

My save_config command didnt works good. I tried to run it using set -x parameter and found that its hanging at:

+ check_vg_in_lvm vg00
+ [[ 0 -eq 0 ]]
+ process_lvm_volume_group vg00

at this line. My disk configuration is good. All LVM related commands like bdf, lvlnboot etc. responds in good way. No network mounts in system. There is no device which is tagged as NO_HW in ioscan output.

In short everything is looking fine still command got stuck at process_lvm_volume_group line.

System info:

rp7400
HPUX 11.00
Ignite-UX-11-00 C.7.2.94 (latest for hpux11.00)

Any comment???

Yea also there are no hardware issues on system and no errors into syslogs.

is there a unconfigured disk in the system . ?

a disk without lvm information may cause this ?

look at disk by "pvdisplay ... "

No all disks are configured on system.

Re: Save_config not responding

Shrikant Lavhate — Wed, 28 Nov 2007 09:14:12 GMT

All disks are properly configured and listed correctly under lvmtab file.

Any other solution ?? Hasan or anybody...?

hi ;

you have probably a problem in "lvdisplay -v lvnames" .
it is possible to put all "lvdisplay -v ..." to a file and upload. ?

Hasan.

Re: Save_config not responding

Shrikant Lavhate — Wed, 28 Nov 2007 10:37:15 GMT

Hasan,

I already mentioned in this thread that all lvm commands are running smoothly. I chked now also and found no problem in lvdisplay of every lvol in vg00.

Hasan Atasoy — Wed, 28 Nov 2007 15:23:48 GMT

hi ;

did you notice any format differences in lvdisplay output ?

Hasan.

Re: Save_config not responding

Shane Seymour — Wed, 28 Nov 2007 22:05:47 GMT

The line:

+ process_lvm_volume_group vg00

is a function call to a function called process_lvm_volume_group. The posix shell does not keep set -x active through a function call. You might consider placing set -x at the start of the function call and see where it stops in that function.

If save_config has stopped when it has ran the get_system_info command run save_config as follows:

# tusc -kpaEef -o (output file) \
/opt/ignite/bin/save_config vg00

Note that the output file produced will probably be quite large.

More than likely you have a disk LUN presented to the system that responds to SCSI inquiry commands but does not respond if you attempt to open a read it. Your only choice will be to unpresent the LUN.

Look for the syscall entry that never returns (may take a while but will be towards the end) and if it's a read system call track back the fd to where it was opened and get the name of the device.

Good Luck.

Shane ,

Thanks for the reply. Your command still dont yeild any new things.. same things happening and we dont have any LUN kinda stuff on our server.

Hasan,
There are no such remarkeble odd things in lvdislpay too..!!

Any more suggestions???

Re: Save_config not responding

Shrikant Lavhate — Thu, 29 Nov 2007 07:20:30 GMT

Shane,

I checked out file and got execution is stucking at this line:

[13691] lseek64(5, 8192, 0, SEEK_SET, 0) .............................................................................. = 8192
[13691] read(5, 0x7f7f1040, 8192) ..................................................................................... [entry]

any clue??

Track back the open system call that returns file descriptor 5 to get the name of the file that was opened that read ended up hanging on and you have your device that is causing the hang.

Track back the open system call that returns file descriptor 5 to get the name of the file that was opened that read ended up hanging on and you have your device that is causing the hang.

If it's a FIFO instead of a device find out what process has the other end of the fifo and what it is doing.

The only other advice I'd have would be if you're not sure what you're looking for open a support call.

Someone within HP will then look at the tusc trace. You may also be asked for a debug run of save_config:

# export INST_DEBUG=5
# script
# save_config ...
# exit

The file created is called typescript in the current working directory (look at the script manual page for information on how to change the name). Provide that file to HP and there is another file you should provide: /tmp/*listener.log if it contains anything.
