SR2122-2 configuration rules

10 SR2122-2 IP Storage Router Release Notes

Storage array rules

■Without HP Secure Path the Enterprise Virtual Array is supported with the SR2122-2

accessing only one EVA controller port. This will disable controller failover protection.

■The SR2122-2 fibre channel ports appear as host bus adapters to the Fibre Channel

switches and to all storage arrays.

Fibre Channel switch/fabric rules

■The SR2122-2 should only be zoned with the storage devices that it will access. Zoning

the SR2122-2 with other servers is not supported.

■Disable useBport when connecting the SR2122-2 to C-series switches using MDS

switch firmware v2.01b or later.

■Disable useBport when connecting the SR2122-2 to B-series switches running switch

firmware 3.2.x or 4.4.x or later. Enable useBport for switches running other firmware

versions.

Management software rules

■OVSAM support is limited to property support only. It will identify the device, and by

clicking on it, one can launch the device embedded web server interface or telnet. A device

specific plug-in for the SR2122-2 is available on the OVSAM Website.

■CIM 7 Supports the SR2122’s SNMP management capabilities.

■Management of the storage arrays through the SR2122-2 is not supported. Please use the

recommended application/element manager to configure the storage array.

Updates/Fixes for this release of firmware

Fixes include:

■Memory (mbuf) leak during handling of Async event (RX_LR) during handling of FCIP

link failure.

A memory leak and potential router crash would occur because of a mishandling of a link

failure during an unstable FCIP connection. This problem would never appear during

normal FCIP operations and is fixed in this release.

■An SR2122-2 would “panic” when a standard MIB II polling engine, such as the HP

OpenView Network Node Manager, attempted to SNMP poll the SR2122-2.
