HP StorageWorks EVA4400 iSCSI Connectivity Option (mpx100b) 5.0 (5697-0512, June 2010)

Workaround

The CHAP setup issue will be resolved in a future release of the Linux initiator.

Windows drops the IP connection

Certain I/O workloads can result in LUN removal because Windows has dropped the IP connection.

Workaround

The connection can be restored by rebooting the system. To avoid dropped connections, do one of

the following:

• Reduce the I/O workload

• Use a smaller application transfer size

HP StorageWorks High-Availability Fabric Manager (HAFM) for M-series Fibre

Channel switches does not recognize the mpx100b

The M-series Zoning Manager does not recognize the world wide port names (WWPNs) of the

mpx100b as Fibre Channel HBAs. Instead, the M-series Zoning Manager sees the WWPNs as

switches, so they do not appear as devices to zone.

Workaround

Use one of the following M-series applications to configure zones that include the mpx100b WWPNs:

• For versions earlier than HAFM 8, use Embedded Web Server (EWS).

• For HAFM 8 and later versions, use HAFM Basic.

NOTE:

After configuring the zones, you must update HAFM to include these changes.

The iSCSI name structure is fairly rigid and contains two parts: a type designator followed by a unique

name.
