Proliant CL380
CR3500 Shared Storage Controller.
RAID 5 on Shared Storage.
Two server node.
Linux RH 7.3
KERNEL-2.4.20-28.7.i386
PSP v 7.00 (Proliant Support Pack).
Informix 9.21. UC3.

When I try to read data from shared storage disks,I catch errors on both servers.
On the first server:

kernel: sym53c896-0: SCSI phase error fixup: CCB already dequeued.
kernel: sym53c896-0: handling phase mismatch from SCRIPTS.

And this errors on the second server:
kernel: sym53c896-0: handling phase mismatch from SCRIPTS.
kernel: sym53c896-0:2: ERROR (a0:0) (40-67-20) (0/7) @ (mem 8:00000000).
kernel: sym53c896-0: regdump: ca 10 c0 07 47 00 02 0a 20 40 82 67 80 00 07 00 90 c3 ff c6 08 00 00 00.

So the CR3500 is not (offically?) support on Linux. I'd check the driver source and see if there any indication in the comments that it is written to support a shared environment.

It was designed for Microsoft MSCS. This SW uses SCSI reserve to reserve a LUN for one server and keep the other from accessing it. If you are trying to access the same LUN for 2 servers, it may not be able to handle it.
