lost ISCSI disks after server reboot

[Lucy2009_1]

Hi,
I have a hp-ux server model rx4640. It has bunch of SAN disks thr. ISCSI connection.
After a server reboot, those disks are not there. "ioscan -fnC disk" does not show.
I also did "insf -H 255" that did not help.
Restarted iscsi daemons and that did not help. I checked the SAN side, all LUNS are online.
The ISCSI NIC is up and pingable.
What could be the problem?

Thanks in advance,

Hi idt,

A target device cannot be seen from the HP-UX host, verify that the iswd daemon is alive by executing

# ps -ef | grep iswd

If the iswd daemon is not alive, restart the daemon and re-issue an ioscan by executing

# /opt/iscsi/bin/iswd

# /usr/sbin/ioscan -NH 64000

#tail -30f /var/adm/syslog/syslog.log
See the error message

check the iSCSI switch and converter.

Thanks all for the input. Another reboot helped to see all ISCSI disks. Don't know where the glitch was.
