Solution 1022254.1 : Brocade Upgrade may Result in Switch Reboot Failure

1. Impact

When a DCX, DCX-4S or Brocade 5300 is upgraded the Control Processor (CP) blade may fail
to gain HA-Sync. When this occurs the processor fails to reboot and the switch fails to come online.

2. Contributing Factors

This issue can occur on the following platforms:

Brocade Fibre Channel Switch without FOS 6.2.2b firmware as delivered in Sunsolve Patch 140810-08
Brocade Fibre Channel Switch without FOS 6.3.1a firmware as delivered in Sunsolve Patch 142801-03

Notes: This issue only affects the DCX, DCX4-S and 5300 and only occurs when upgrading from:

- FOS v6.1x

- FOS 6.2.0x

- FOS 6.3.0x

To determine the firmware level of the switch type, use the "version" command at the command line.

3. Symptoms

The upgrade operation fails and the Compact Flash (CF) may report an access error.

The CP blade within a DCX or DCX-4S will fail to reboot completely.

For the Brocade 5300, the switch fails to reboot.

This failure is accompanied by the message, “HDA: Device not ready” from the serial console output.

4. Workaround

There is no recovery when this occurs and you will need to contact your normal support channels.

5. Resolution

This issue is addressed with the following releases:

Brocade Fibre Channel Switch with FOS 6.2.2b firmware as delivered in Sunsolve Patch 140810-08 or later
Brocade Fibre Channel Switch with FOS 6.3.1a firmware as delivered in Sunsolve Patch 142801-03 or later

Note: Using the above as the upgrade path will avoid the issue.

If the Compact Flash was corrupted due to a timing violation during an access sequence, the unit will
fail to recover after attempting a cold reboot. In this case, replace the Brocade 5300 or affected CP
within the DCX or DCX-4S.
