HP P2000 Release Note page 14

will be recorded in the event logs: "An unsupported cable or SFP was inserted". At the same time, the host port will not
show a status of "Down".
Workaround: Do the following:
1. Verify that the SFP+, Copper Cable, or Direct Attach Cable is a supported component. For support information, see the
P2000 G3 QuickSpecs on the P2000 G3 product page: http://www.hp.com/go/p2000.
2. If the components are indeed listed as supported models, remove and reinsert the SFP+, Copper Cable, or Direct Attach
cable.
3. If this does not correct the issue with the SFP+, Copper Cable, or Direct Attach Cable connected to the controller, either
remove and reinsert the controller or power down and reapply power to the array.
Issue: RHEL 5 Update 5 will not shutdown properly when using the iSCSI initiator utilities shipped in RHEL 5 Update 5 to
access the array.
Workaround: See issue 583218 on the Red Hat Bugzilla bug-tracking system
id=583218 for the current status of the issue and possible workarounds.
Issue: When using explicit LUN mapping, using long IQN names for the iSCSI Initiator can cause the array to map the
LUN incorrectly. A predefined area is used to store explicit LUN mapping information per LUN and, with longer IQN
names, this area can be exhausted. This issue is not dependent on the number of paths to the LUN.
Workaround: Shorten the IQN name on the nodes.
The following formula is used to calculate the maximum IQN name length based on the number of hosts being explicitly
mapped to a LUN on the array:
Maximum IQN Character Length = (4083 / n)
a LUN on the array.)
NOTE: By specification, 223 is the maximum IQN length allowed.
The following table provides the calculated values based on the number of hosts being explicitly mapped to a LUN on the
array:
