Server Rebooted... IOSCAN returns NO RESULTS

[Michael Burns_7]

we rebooted an HP-UX server last night and this morning we get no results what so ever....

any thoughts?

[Peter Godron]

Michael,
when you rebooted the server any error messages? It must have recognized something, otherwise how did it boot (system disk).
So ioscan comes back with NOTHING?
Try stm and come back with your findings.
Thanks

Hi

Maybe ioscan is corrupt or another file called ioscan in the PATH


/usr/sbin/ioscan -nf

ll /usr/sbin/ioscan

Please define what doesnt work

does bdf work

Hi,

compare 'which ioscan' with the informations you got above about the ioscan-path.

/usr/sbin/ioscan gives no results.

bdf sees all the mounted volumes... but is not seeing the tape devices... which are in fact working...

ioscan -fnC tape does not find any tape devices... these are fiber attached tape drives in an HP library

Are your connections zoned? If they are you might want to make sure that they are zoned properly.

[Florian Heigl (new acc)]

rough guess - your running kernel has gotten out of sync with the userspace binaries.

look through /var/adm/sw/swinstall.log and see if there were any ioscan- or kernel spefific patches installed while ignoring the dependencies.
consider building a new kernel for testing purposes if downtime is available (do an ignite backup before, just in case...)

Hi,

Try lssf /dev/rmt/????, can you see the HW path of the tape drive?

Try restarting the tapedrive/library then run ioscan -fnC tape.

I have the same experience but it is a DDS tape drive. I cannot find the tape drive using ioscan, when i run lssf /dev/rmt/0mn it saya "HW located at ???". I just power off/on the tape drive then run ioscan -fnC tape.

Hope that helps,

Regds,
Paul

Try running "whence -v ioscan" on this machine, and also on another machine running the same OS version. Then compare the paths, dates, sizes & checksums of the ioscan binaries.
If your ioscan binary has been corrupted, you should just be able to copy one from another system.

try these:

1.whereis ioscan

2.cksum ioscan---->
# cksum ioscan
937153911 229376 ioscan
output wil like this.

3.ioscan -fn --- Outout ???

see your HSC SCSI cntrlls are detected


good luck

Got a real Unix Admin on site to help me out last night. He was able to resolve using information from these replies as well as his own.

THANKS!
