1.) It might be an IOSCAN problem, install
the latest ioscan patch.

2.) IOSCAN normally takes some time (few
seconds) based on the hardware configuration,
as it searches to find any hardware changes
(additions & deletions), so this is normal.

3.) If your intention is not scan the H/W, but
just get the existing H/W-driver list then
try using ioscan -k OR ioscan -u.

There can be some problems with your H/W
configuration. Try to find where is this
problem using ioscan for different groups of hardware: disk, lan, ....

#ioscan -fnC disk
#ioscan -fnC lan
...
...

This way you could localize the problem.
Check existing of files:
/etc/ioconfig
/dev/config

Hi,
Ioscan hangs due to improper cabling (connecting storages boxes to your server) like no proper termination, loose connections etc.

Check that once.
Hope that helps.

I guess some reason:
1. You lack of some OS patches. Check it by using release note.
2. Check file system capacity by bdf (if some file system is full all command will hang, not only ioscan)
3. Check syslog to determine the health of Hardware.

run #mstm

push 'o'
go to "tools" -> "utility" -> "logtool"

And read the instructions there.

Then create a summary log.

Any hardware problems will show.
