Hi,
We have a Solaris 8 machine connected to an IBM SVC (version 4.1).
Behind the Ibm Svc there's a DS8300 storage cabinet.
The Sun machines has Sun branded Qlogic cards (QLA2310F-SUN), we are
using the qlc-driver for the hba's and the Ibm sdd driver in stead of
mpxio.
We also use Disksuite (SVM) as volume manager.
We faced some strange problems when connecting the Sun to the Ibm
storage.
In the Ibm documentation there is a procedure to discover new luns
online.
Unfortunately when we try is (devfsadm; rm /etc/vpath*cfg; cfgvpath -c ;
/etc/rcS.d/S65vpath-config) we will see the new luns and we can add a
new filesystem.
But after a reconfigure reboot all the disks are reshuffeled :-(
When we don't try to discover the new luns online, just map the disk and
do reboot -r everything is fine.
Don't like it to reboot a server for discovering a new luns, but for
this a fact of live.
Did anyone had same problems?
In the Ibm documentation we cannot find anything about the qlc driver,
only the qla2x00.conf is mentioned.
Does someone know how to set persistent binding on the qlc driver?
I'm also wondering if anyone has a Sun box connected to Ibm Svc. What's
your experience with it?
Many thanks.
Klaas
