Can't see new disk after ioscan

[WSS]

Hi there,

I was wondering if there was a way to see some new disk that has been presented to one of our servers, without having to reboot.

I have had some unwanted disk devices taken away from the EMC, and one additional disk added, but when doing an ioscan -funC disk, I am not seeing anything different. ioscan still reports on all the devices that it did before the changes were made to the EMC (changes not made by me)...

Running HP-UX 11i Rx4640 servers, with the disk being on EMX storage arrays.

Is there a way I can see the disk without having to reboot?

Thanks in advance.

Hi WWS,
It is not necessary a reboot after installing EMC disk on HP-UX.
With ioscan and insf should be enough.
The problem could be the ZONE.

Shalom,

HP storage usually does not require a reboot. Other vendors do.

Try

insf -C disk

The usual problem with this is the disk isn't properly presented to the correct WWN, Worldwide Name by EMC configuration.

fcmsutil -remote -all (see the man page this one is fuzzy in my pea brain molecules)

This should show you everything including proerly assinged LUNS.

Steven, will running insf mess about with any of my current disk structure, re is it totally safe to run at anytime?

run insf -e -C disk, this should put out the driver for the new disk.

Try running ioscan w/o any arguments and see if the new disk shows up. Another thing you can do is to lookup the tail end of the syslog file and see if any new devices were logged in there owing to the ioscan.

Exactly,
ioscan -funC disk doesnt rescan for new hardware, ioscan without argument does...

All the best

Hi WWS,

verify SAN zonning.

If you have "symcli,

and on HPUX server:

# symconfigure
# symmask
# ioscan -fnC disk
# insf
# symcfg discover

It might also help if you use 'ioscan -fnC disk' instead of 'ioscan -funC disk'.

man page for ioscan:
" -u
Scan and list usable I/O system devices instead of the actual hardware. Usable I/O devices are those having a driver in the kernel and an assigned instance number. The -d, -C, -I, and -H options can be used to restrict listings. The -u option cannot be used with -k."

Then when you find it with ioscan, 'insf -e' should install the necessary device files.

Good luck.

Kind regards,
David de Beer.

Hi ,

Dont use ioscan -funC disk as it gives the result from the cache .

Use ioscan -fnC disk which does a fersh scan on the hardware and hopefully it should show your added disks.

Thanks,
Siva
