RTWR (Reliable Transport Write and Read) messages get logged when more than 16 dynamic paths are set up to remote domains on HP 8 Gb switches. Customer may experience path loss and traffic interruption. Fixed in Fabric OS 6.3.1 Workaround prior to upgrade: Limit the number of dynamic paths on these platforms. Note: if there are more than 16 dynamic paths already on these platforms, upgrade to 6.3.1 may be a cold recovery. When small read requests (low I/O rate traffic) sent via FCIP tunnel, a 2 - 4 ms delay can be seen between the time data arrives on the GE port until it's sent out the FC port, leading to >10 ms response time. Fixed in Fabric OS 6.3.1 Workaround prior to upgrade: Refrain from using low I/O rate traffic. HP 10/24 FCoE blade gets into faulty (21) mode during stress testing Fixed in Fabric OS 6.3.1 due to backend port fault. After a target port bounce, the FC FastWrite host cannot recognize Fixed in Fabric OS 6.2.2a the target due to a cam setup problem on the backend port used by FC FastWrite. Fixed in Fabric OS 6.3.1 HP StorageWorks DC SAN director with 10/24 FCoE blade crashed while attempting to change TE Port from LAG (Link Aggregation) to trunk Fixed in Fabric OS 6.3.1 mode. While running Fabric OS 6.2.2, the switch can panic after executing a fcplunquery or iscsicfg CLI command for the target entity on HP StorageWorks iSCSI Director Blade. An FCPd termination occurs if a PRLI or Report LUN query times out during fcplunquery/iscsicfg command and the LOGO response is missing a message queue required for processing, resulting in a switch panic. Fixed in Fabric OS 6.3.1 When an HP 10/24 FCoE blade is installed in the highest number slot Fixed in Fabric OS 6.3.1 in a DC SAN director or DC04 SAN director, it will not send out any Workaround prior to upgrade: Move UA's (Unsolicited Advertisements), so FCoE traffic will not occur. 10/24 blade to a lower number slot. Switch displays incorrect information upon userconfig --show command execution. Changes to admin password on a switch are not being recorded properly (password last change date shows incorrect date). Fixed in Fabric OS 6.3.1 I2C read values of 0xFF and I2C NACK error case not properly handled Fixed in Fabric OS 6.3.1 causing Fabric Watch to report improbable/unpredictable SFP values. The configdownload command does not load tstimezone info after changing tzh and tzm in the config.txt file to new values.

After upgrade to Fabric OS 6.x, rsh using user credential gets ifmodeshow eth0: ioctl (ETHTOOL_GSET) failed error in response to ifmodeshow command. Telnet and rsh with root credential work fine. Fixed in Fabric OS 6.3.1 Workaround prior to upgrade: Set suid permissions for ethmode: chmod +s /fabos/libexec/ ethmode 4 Gb SFPs do not consistently show data in sfpshow on HP StorageWorks 1606 Extension SAN switch ports. Sfpshow reports cannot read serial data, or incorrect serial number, or no serial number at all Fixed in Fabric OS 6.3.1 82
