Solution Type Sun Alert Sure Solution 1000043.1 : Changing the Array Volume-to-LUN Mappings May Cause Array Controllers to Initiate a Boot-Loop
PreviouslyPublishedAs 200057 Product Sun StorageTek 5310 NAS Appliance Sun StorageTek 5320 NAS Appliance Sun StorageTek 6130 Array Sun StorageTek 6140 Array Sun StorageTek 6540 Array Bug Id <SUNBUG: 6542513> Date of Preliminary Release 03-MAY-2007 Date of Resolved Release 21-Oct-2008 Changing the Array Volume-to-LUN Mappings May Cause Array Controllers to Initiate a Boot-Loop 1. Impact For Sun StorEdge/StorageTek arrays with certain firmware, changing the array volume-to-LUN mappings may cause array controllers to initiate a boot-loop and immediate loss of access to the arrays. 2. Contributing Factors This issue can occur on the following platforms:
Note: Firmware version 06.19.23.10 is released with Sun StorageTek Common Array Manager (CAM) 5.1. This issue presents itself after manipulating the volume mappings on the array via the host mapping interface, or by the creation or deletion of Remote Replication sets. 3. Symptoms
Management hosts attempting get status information from the array will get a communication error. This error can vary, since the controller boot cycle can allow brief connections via the user interface. Communications errors may present themselves during any activity. For 5310 and 5320 NAS Appliances, users will be unable to access shares or NFS export filesystems. The best way to identify the boot loop issue is by connecting to the array via the serial port, and observing any messages that appear. The message signature are similar (but not limited to) the following, and are easily identified by the scrolling nature of the messages: 03/30/07-14:45:51 (GMT) (tRAID): NOTE: CCM: MirrorInit, clearing MOS (2) 03/30/07-14:45:56 (GMT) (tRAID): NOTE: Volume discovery... 03/30/07-14:45:56 (GMT) (tRAID): NOTE: Scanning usable NATIVE drives 03/30/07-14:45:59 (GMT) (ssmTimer): NOTE: CCM BMG: Battery is OK 03/30/07-14:46:01 (GMT) (tRAID): NOTE: evf - Peering Disabled (Alt in SOD) 03/30/07-14:46:01 (GMT) (tRAID): WARN: -=<###>=- Attaching interface lo0...done Adding 7246 symbols for standalone.

Workaround It is recommended to update to 06.19.25.16 as soon as possible, as it includes additional debugging for this issue. Note: Reverting to an earlier revision of the firmware is not advised since this would cause the loss of other fixes bundled into this version of the firmware. Note: With the above
mentioned update, the array will now capture a Diagnostic Data
Collection when the condition occurs. The data can be collected after
the issue is reported and corrected. By design, the data collection
will turn on the global fault LED on an array when the data is present
for download. If your system has experienced this issue, do a
Diagnostic Data Collection capture and contact Sun Support. 5. Resolution Please see the "Workaround" section above. This Sun Alert notification is being provided to you on an "AS IS" basis.
