I have a problem with linuxRDAC failover on RHEL 3.0 AS, update 6 with Qlogic HB 2005-12-06 - By JAJA (Jamie Jamison)
Back
I have an Oracle cluster consisting of two Dell 6650s each with 2 Qlogic
2340 HBAs connected to a StorageTek D178 array. I'm running update 6
with the 2.4.21-37EL-hugemem kernel. When I install the Engenio
LinuxRDAC software it only sees one of the HBAs, controller B. I can see
the LUNs on both HBAs from the firmware utility and also from the
operating system when I run the scli utility that comes with the
Engenio software, but despite this only one controller works. The only
clue I have is that when I look in
/proc/scsi/qla2300 I see the following entries.
__ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ __
#cat /proc/scsi/qla2300/2

So on the one controller the LUNS are not registered with the OS. Is
this a clue? How do I get these LUNs to register with the OS? Any help
will be greatly appreciated.
Thank You,
Jamie Jamison
