HP B-series Fabric OS 7.1.1a Release Notes (5697-3023, November 2013 - includes all 7.1.1x versions)

• Special Notes for HP Data Protector backup/restore application:
For the Tape Pool encryption policy specification on Windows Systems, HP Data Protector
can be used with tape pool encryption specification only if the following pool label options
are used (for other options, behavior defaults to Tape LUN encryption policy):
◦
– Pick from Barcode.
– User Supplied. A maximum of nine characters.
◦ On HP-UX systems, HP Data Protector cannot be used with tape pool encryption
specification for any of the pool options. The behavior defaults to Tape LUN Encryption
Policy.
◦ For the Tape LUN encryption policy specification, no restrictions, tape LUN encryption
policy specification can be used with HP Data Protector on HP-UX and Windows systems.
• HP StorageWorks Encryption SAN Switch/HP StorageWorks DC Switch Encryption FC Blade
rejects the SCSI commands write same and extended copy, which are related to VAAI
(vStorage APIs for Array Integration) hardware acceleration in vSphere 4.1. This results in
non-VAAI methods of data transfer for the underlying arrays, and may affect the performance
of VM related operations.
• VMware VMFS5 uses ATS commands with arrays that support ATS. The HP StorageWorks
Encryption SAN Switch/HP StorageWorks DC Switch Encryption FC Blade do not support
this command set and therefore VMFS5 with ATS is not supported. Instead, HP recommends
that you use VMFS3.
FCIP (HP DC SAN Director Multiprotocol Extension Blade, HP 1606 SAN Extension Switch and
HP StorageWorks B-series Multi-protocol Router Blade)
• Any firmware activation disrupts I/O traffic on FCIP links.
• Latency measurements supported on FCIP Tunnels are for 1 GbE & 10 GbE a 200 ms round
trip time and 1% loss.
• After inserting a 4 Gb/s SFP in GE ports of an HP DC SAN Director Multiprotocol Extension
Blade or HP 1606 SAN Extension Switch, sfpshow output might display Cannot read
serial data!. Removing and re-inserting the SFP should resolve this issue. HP recommends
that users perform sfpshow immediately after inserting the SFP and make sure SFP is seated
properly before connecting the cables.
• When running Fabric OS 7.0.0a or later, if any of the following features are enabled in the
FCIP configuration, a downgrade operation to pre-Fabric OS 7.0.0a is blocked until the
features are removed from the FCIP configuration:
◦ Inband Management
◦ Multigigabit Circuit
◦ Shared GE among Logical Switches
◦ Auto-mode compression option
◦ VE as XISL
◦ 10 GigE lossless failover
◦ Modified QoS percentages
◦ 10 GigE ARL
◦ IP Configuration where multiple GigEs have same subnet values
