RHEL 5.2, Multipath to EVA 6000
Hi all
I'm trying to access an EVA6000 from a RHEL 5.2. I've installed HP SupportPack "psp-8.15.rhel5.x86_64.en.tar.gz" and the Redhat Multipath package "device-mapper-multipath-0.4.7-17.el5".
To configure the multipath software I followed the HP Release Notes at http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01496537/c01496537.pdf
Using the HP Fibreutils I can see the presented disks:
#/opt/hp/hp_fibreutils/hp_rescan -a

scsi1 00 04 00 HP HSV210 6110 RAID
scsi1 00 05 00 HP HSV210 6110 RAID
I then executed a dry-run with the multipath command, everything seems to be ok:
# multipath -d
create: u01 (3600508b400100c4e0001500000850000) COMPAQ,HSV110 (C)COMPAQ

\_ 1:0:0:2 sdf 8:80 [undef][ghost]
\_ 1:0:1:2 sdh 8:112 [undef][ghost]
But when I run the command without the "dry run" switch, nothing happens, the expected multipath devices are not created.
In the kernel log the following error messages can be found:
Jan 29 10:46:03 lxpwi101 kernel: device-mapper: table: 253:10: multipath: unknown hardware handler type

My multipath.conf:

}

Any idea?
