Strange DM issue on boot
 
EL 5.2
Hitachi AMS1000 array
Qlogic HBA (qla2xxx driver)

I am seeing a strange issue when rebooting a server connected to the
AMS1000 disk array. If I have a mount point defined in /etc/fstab that
points to a mulitpathe device I receive the following error:


error calling out /sbin/mpath_prio_hds_modular 8:32

That error would seem to indicate a path failure, but if I remove the
entry from /etc/fstab and reboot I am able to mount the device from the
command line. I have tried to include the qlogic driver in the initrd,
but that did help in any way. Are the dm-multipath drivers loading at
the incorrect time? Has anyone ever encountered this before?


Regards,

Sajesh

The controllers are not happy with the panging on the controllers.

Charles,
Thanks for the quick reply, do you mean that the controller
is reporting incorrect information to the multipath modules? I have the
same setup on CENTOS 4.6 servers with no issues.

Should I not be using the default settings in the /etc/multipath.conf?
Are there any specific settings that need to be configured to use
multipathd with an HDS AMS1000 array?
