HP 1606 HP StorageWorks Fabric OS 6.3.2b Release Notes (5697-0777, November 20 - Page 47

After doing a firmware upgrade or an hafailover on a 4/256 director with 4Gb 48 port blade installed, the CP blade faults and traffic is disrupted. External RASLOG EM-1051 messages are seen, reporting a slot inconsistency detected. This can occur if a PLOGI is received right before the hafailover or hot code load and it has zone misses for devices communicating through the primary shared area port. Fixed in Fabric OS 6.3.2a. Port zoning enforcement cycles between session based zoning and hard zoning. This can happen when name server queries occur at the same time as a zone configuration change is initiated. ZONE-1004 messages are seen in RASLOGs but no traffic interruption is observed. Applies to all platforms. Fixed in Fabric OS 6.3.2a. When standby CP is not responsive (stuck in reboot loop) on any director class switch, Weblinker causes the active CP to reboot, leading to a Fixed in Fabric OS 6.3.2a. cold recovery. FICUD ASSERT/auto-reboot occurs when changing logical switch configuration due to random timing condition in accessing switch configuration data. Observed when running lscfg commands to configure FICUD ports. Both CPs reboot with disruptive recovery. Fixed in Fabric OS 6.3.2a. Race condition in FCP daemon logging mechanism causes memory corruption and panic. This leads to cold recovery during firmware download or when management applications using the SMI client continuously query the switch. Occurs in VF configurations with multiple logical switches configured running Fabric OS 6.2.x and 6.3.x previous to 6.3.2a only. Workaround prior to upgrade: Perform hafailover/hareboot to clean up any existing corruption before code upgrade, then disable FCP logging using fcplogdisable to avoid any further corruption until upgrading to a version of Fabric OS with the fix. Fixed in Fabric OS 6.3.2a. During host reboot, F_Port may come up as G_Port on 4/8, 4/16, 4Gb switch for HP p-Class BladeSystem or 4Gb switch for HP c-Class Fixed in Fabric OS 6.3.2a. BladeSystem. Compact Flash (CF) can sometimes fail silently. In such cases, the user sees only critical daemon failures triggering a failover. Sometimes no failure is seen, and the switch continues running but does not produce any logs. Fabric OS 6.3.2a provides an enhancement to CF failure handling to detect and proactively trigger an hafailover when a bad part is detected. Fixed in Fabric OS 6.3.2a. On 8Gb switches, constant link resets occur when a long distance E_Port port is configured that requires 128 to 511 credits. These link resets occur continuously with no traffic, and a constant stream of C2-5021 indications are seen. Workaround prior to upgrade: Use OOS mode. Fixed in Fabric OS 6.3.2a. Host ports can experience slow performance after enabling and then disabling Top Talker. Class 3 frame rejects can also be seen in the portlogdump. This is due to a residual setting in the firmware that causes class 3 frame rejects to be continuously forwarded to the CPU causing the slow performance. Fixed in Fabric OS 6.3.2a. Switch panics, blade faults, or switches getting disabled when credit loss is detected on internal backend port. RASLOG C-5021 or C2-5021 Fixed in Fabric OS 6.3.2a. indications are reported.
