Software Information and Issues

Main Board, Management Controller, and Chassis Serial Numbers

The switch documentation describes how to retrieve the chassis serial number using the showfruinfo command or the /SYS/MB Oracle ILOM target. These methods actually display the serial number of the main board and the management controller respectively, and not the switch chassis. The switch chassis serial number is provided on the pull-out tab on the left side front of the switch chassis, adjacent to power supply 0.

Firmware Version Numbers

When upgrading the management controller firmware, the procedure uses the variables x, y, z, and w in filename strings to identify the version number. For this release of the firmware, 2.0.8-1, the values are as follows:

• x is 2

• y is 0

• z is 8

• w is 1

Time Zone Support

The following time zones are only supported in firmware versions 1.3.4, 2.0.7-2, and 2.0.8-1. If you upgrade or downgrade to a firmware version other than 1.3.4, 2.0.7-2, or 2.0.8-1 you must set an alternative time zone.

Firmware Update Considerations

If you are going to downgrade the firmware to a version earlier than 2.0, you must remove user partitions and depopulate the Subnet Manager nodes list. Refer to Switch Administration, removing partitions for firmware downgrade.

If you are going to downgrade from firmware 2.0.x to 1.3.4_1 or earlier, you might see these type of messages in the /var/log/message file after the downgrade:

lda: Unknown config parameter: ErrLogCount=100; .

lda: Unknown config parameter: ErrLogTimeInterval=100; .

The ErrLogCount and ErrLogTimeInterval configuration parameters introduced in firmware 2.0.x are unknown to firmware version 1.3.4-1 and earlier LDAs. The LDA logs these messages and ignores them from there on. The messages appear once per LDA startup and are harmless.

If you later upgrade from firmware 1.3.4-1 to 2.0.x and the ErrLogCount and ErrLogTimeInterval configuration parameters are absent, the 2.0.x LDA uses the compiled default values. Consequently, no LDA messages regarding these configuration parameters are recorded.

High Availability in Partitions

To allow communication fail-over between HCAs belonging to the same operating system instance, the HCA ports must be members of the same partition and have identical membership type (full or limited).

Having both full and limited port memberships within a partition for the same operating system instance creates a configuration instability that might cause subtle communication problems.

Email Alert Rules

It is mandatory to specify the value for the email_custom_sender property of an email alert rule. It does not use the custom_sender property of the /SP/clients/smtp target.

Commands Available to Restricted Linux Shells

Typing help all within either the /SYS/Switch_Diag or /SYS/Fabric_Mgmt restricted Linux shells lists the commands available to those shells.

In the output, the checkguidfilesftree command is listed, however, the command is not supported.

Conversely, the fdconfig command is not listed in the output, but is supported by the /SYS/Fabric_Mgmt restricted Linux shell.
