HP StorageWorks EVA iSCSI Connectivity Option Release Notes (5697-5472, February 2006)

IMPORTANT NOTES AND WORKAROUNDS:
The following sections list important notes and worka round solutions.
Windows IP connection
Important no
te—Windows dropping the IP connection
Certain I/O
workloads can result in LUN removal because the Windows operating system has dropped
the IP connection
Workaround
The connection can be restored by rebooting the system. Select one of the following options to avoid
dropped connections:
• Reduce the I/O workload
• Use a smaller application transfer size
Continuou
s Access
Important note—Continuous Access is not supported in both direct at tach servers and direct
attach iSCSI solutions
Workaround
When usin
g Continuous Access EVA , all host por ts must be connected to an approved Fibre Channel
switch. HP supports directly connecting an EVA to mpx100s or ser vers as long as the solution does not
involve remote replication. This applies to any EVA3000/5000 or EVA 4000/6000/8000 that is
licensed for Continuous Access EVA. For more information on how to attach an mpx100 or a server to an
EVA stor
age system, see the HP StorageWorks EVA iSCSI connectivity user guide.
Windows MPIO
Important note—when a path is lost to a target, the Microsoft initiator does not re-log in to
the target after the path becomes available
Microsoft V2.0 MPIO does not have any polling functionalit y to query the target when it becomes
available. The Target status is inactive and the total path count is reduc ed until the initiator re-logs in
to the t
arget manually.
Workaround
1. Select the Inactive target under the Select the Inactive target under the Targets tab.
2. Click Log On.
3. Click on the Enable Multipath checkbox
4. Click OK.
NOTE:
Do not click on the Automatically Restore checkbox, because this creates a duplicate tar get entry
under the Persistent Targets tab.
