Storage and Adapter Configuration
Item Description
DataCore SANsymphony
This storage device was successfully tested
with SUSE SLES 9 Service Pack 3, Device
Mapper - Multipath and Qlogic 2340 adapters.
We expect that it should work with other
versions, distributions and adapters; however,
this has not been tested. See DataCore for
specific support for these and other
configurations.
One issue was found during failover testing with
heavy stress running where multiple server
reboots would result in a server only configuring
a single path. The test configuration consisted
of a 3-node cluster where 2 servers would be
killed simultaneously. After the 2 servers
rebooted, about 50% of the time one server
would only have a single path configured. A
reboot of the server would resolve the problem.
This issue was never seen when only a single
server was rebooted. This issue has been
reported to DataCore. This item is not
considered a critical issue since at least one
path continues to be available.
Xiotech Magnitude 3D
This storage device was successfully tested
with Red Hat EL 4 Update 3 and Qlogic 2340
adapters. We expect that LifeKeeper would also
work with other versions, distributions and
adapters; however, this has not been tested.
See Xiotech for specific support for these and
other configurations.
The Magnitude 3D was tested in a single path
configuration.
During setup, one configuration issue was
detected where only 8 LUNs were configured in
the OS. This is due to the Magnitude 3D
specifying in the SCSI inquiry data that it is a
SCSI-2 device. The SCSI driver in the 2.6
kernel will not automatically address more than 8
LUNs on a SCSI-2 device unless the device is
included in its exception list. The Magnitude 3D
is not in that list. Xiotech provided a workaround
for testing to issue a command to /proc/scsi/scsi
to configure each LUN.
