Hi,
In a Linux cluster setup, I have some issues.
I am trying to use 'md' driver in Linux for multipath
to shared storage with Enterprise Virtual Array 3000
(EVA 3000)
i believe someone from HP already stated in this list that md driver
(multipath) does not work with EVA, i guess do to issues with
preferred path.
Do I still need to use the Driver Patch for EVA
Controller Failover?
i believe using the qlogic driver failover is a viable solutio, another
is purchasing securepath from HP. but i believe there were issues using
securepath and lvm together.
The MC/SG spec says that 'md' driver should not be
active at the same time on both the cluster nodes. So,
I am not using the 'fd' type of partition which starts
the arrays at boot time. I just use the default 83
type.
Is there any specific need to update to 2.6 kernel in
order to support LVM 2?
i don't know if that is supported by either hp or suse.
The kernel version of the O/S in the cluster nodes is
2.4.19 which contains lvm 1.0.5-51. It does not
support 'pvremove' and probably the tool 'mkraid' does
have some bugs. No idea if there are fixes for the
same. Is it better to use 'mdadm'?
i do personallu prefer mdadm to mkraid.
Any hints/suggestions would be appreciated.
also try asking in the hp itrc forums.
