hi all,
often i'm having problems with 6 server HP blade with linux 5.5,
in dmesg i found this error:

You seem to be using device-mapper-multipath (dm-multipath for short). The error messages seem to indicate some sort of trouble with your first QLogic HBA.

> sd 0:0:0:0: SCSI error: return code = 0x00070000

This code seems to mean "internal error", reported by the HBA driver. So the problem would most likely be in the driver, firmware or hardware of the HBA.

Go to the support website of your SAN manufacturer and find the compatibility list/database. It may list some specific minimum version requirements for the Linux kernel, HBA driver, HBA firmware or storage firmware. It may also list some requirements on HBA or storage configuration. Make sure all these requirements are met.

environment effected

Red Hat Enterprise Linux 5 (RHEL5) update 3 and earlier
QLogic HBA card using qla2xxx driver provided by Red Hat Enterprise Linux kernel.
device-mapper-multipath to manage multiple SAN paths.

Resoln:
Upgrade to kernel-2.6.18-164.el5 which contains a fix, allowing specific errors to be retried without failing the path.
This issue is also fixed in rhel‑5.3.z kernel-2.6.18-128.1.10.el5.

Please check the firmware on the HBA, we had similar problems and they were gone after upgrading the HBA firmware .
