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.
