Re: HPUX 11.31 ioscan not showing disks
I got the below output..
--------------------------------------
bhpux1131_old# type ioscan
ioscan is /usr/sbin/ioscan
bhpux1131_old# file /usr/sbin/ioscan
/usr/sbin/ioscan: PA-RISC1.1 shared executable -not stripped
bhpux1131_old#
--------------------------------------
on the same machine whe I executed "setboot" I got the below results..
---------------------------------
bhpux1131_old# setboot
Primary bootpath : 0/1/1/1.0x2.0x0 (/dev/rdisk/disk7)
Alternate bootpath : 0/0/2/0.0.0x0.0x0 (/dev/rdisk/disk4)
Autoboot is ON (enabled)
Autosearch is ON (enabled)
bhpux1131_old#
----------------------------------
then I did scan on that H/W path and I got,
----------------------------------
bhpux1131_old# ioscan -H 0/1/1/1
H/W Path Class Description
=======================================
0/1/1/1 ext_bus SCSI C1010 Ultra160 Wide LVD
bhpux1131_old#
bhpux1131_old# ioscan -H 0/1/1/1.0x2.0x0
bhpux1131_old#
Thanks,

Re: HPUX 11.31 ioscan not showing disks
running 'ioscan -fnNC disk' gives the below output on the machine, which shows the disks..

Still curious to know why normal "ioscan -f" is not displaying the disks... Is it an expected behavior is 11.31 ?
nyways, thanks for pointing me to the correct command...

Re: HPUX 11.31 ioscan not showing disks
Something is really wrong with this system.
This is not expected behaviour!
From a similar system (same OS):
#ioscan -f
Class I H/W Path Driver S/W State H/W Type Description
==============================================================================
...
ext_bus 2 0/1/1/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD
target 1 0/1/1/0.0 tgt CLAIMED DEVICE
disk 1 0/1/1/0.0.0 sdisk CLAIMED DEVICE HP 36.4GST336753LC
target 0 0/1/1/0.1 tgt CLAIMED DEVICE
disk 0 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 36.4GMAS3367NC
...
#ioscan -t

/dev/rdisk/disk32 /dev/rdsk/c2t1d0
Hope this helps!

Re: HPUX 11.31 ioscan not showing disks
Me too think the same - there is something wrong with this machine... I checked all other 11.31 machines we have.. all these machines are showing disks in the "ioscan -f" output. But none of those machines are rp3410 (the model on which I'm facing this issue).
Anybody out there who has rp3410 running 11.31, please check if normal ioscan shows disks...
one more thing I noticed is the difference in the H/W path. in all other machines it shows something like 01/2/3/4.0.0 but only in this machine (rp3410) the H/W path for disks are shown as 64000/0xfa00/0x0

Re: HPUX 11.31 ioscan not showing disks
The different format is the new layout vs. the legacy. Different options for ioscan (e.g. -N) will produce different output.
I would consider to "repair" the system by doing new install - who knows what else is wrong now...
Hope this helps!
Regards
Torsten.

Re: HPUX 11.31 ioscan not showing disks
The hardware path differences you noted are due to the agile view showing the persistent device file rather than the legacy device file. See the man page for intro(7):
"A persistent device special file is associated with a LUN hardware path, and thus transparently supports agile addressing and multipathing.
.
.
.
A legacy device special file is locked to a particular physical hardware path, and does not support agile addressing. Such a device special file contains hardware path information such as SCSI bus, target, and LUN in the device file name and minor number. Specifically, the class and instance portions of the device special file name indicate hardware path information and are in the format c#t#d#"

Re: HPUX 11.31 ioscan not showing disks
Chechk that the sdisk device driver is in the kernel (I can't believe it won't be though):
kcmodule -v sdisk
Is tjere actually anything in the /dev/[r]dsk/ directories?
ls /dev/*dsk/*
lssf /dev/*dsk/*

Re: HPUX 11.31 ioscan not showing disks
Think I have it figured out now - see p12 of this whitepaper:
http://docs.hp.com/en/dsfmigration/persistent_dsf_migration.pdf
The section entitled "Disable Legacy DSFs"
I'm guessing that someone has run:
rmsf -L
You can check whether this is the case by running:
insf -L -v
If it states that Legacy mode is disabled, then I'm right.
Seems you can re-enable legacy DSFs using:
insf -L
