EVA 4400 Redhat Linux 5.1
Here are the details of the EVA 4400
xcs 090006000
Management Module firmware mmp-0001-1000-000117R
The machines are
DL380 G5
Redhat Linux 5.1
Qlogic Failover Driver v 8.02.11-2
Lifekeeper is installed on both machines
Description of problem:
Server A and Server B are both presented 2 luns each. Both machines have SCSI2 reservations on their respective luns.
If Server A experiences a full disconnection from the fabric (i.e. dual fiber break) and Server B puts a SCSI2 reservation on the luns (i.e. lifekeeper software fails the devices over to server B). Then server A will not see the devices when it's reconnected to the fabric.
The only way to clear the SCSI2 reservations is to neuter the failover software (lifekeeper), reload the qlogic driver, and do a hp_rescan for the luns.
Has anyone else experienced such a thing? Is there a better way of doing this (i.e. Device Mapper?)
Thanks in advance,
Mike

Re: EVA 4400 Redhat Linux 5.1
When I view /proc/scsi/scsi on a reboot of the machine, there is nothing listed at all.
If I do an hp_rescan -a, it brings back the luns, however the partitions created are not listed in /proc/partitions
It's only when I use Lifekeeper to remove the scsi2 reservations, that I can rescan the luns, and get the proper partition information.

Re: EVA 4400 Redhat Linux 5.1
That is good news that someone with a slightly different architecture is experiencing the same symptoms.
I am wondering if his case is possibly based on our case as we opened a case with HP from two angles (one from our office and one from steeleye)
