1. Impact
Sun StorageTek 25x0 and 6140 arrays with certain firmware may send
wrong network packets to the network. This can cause the Sun
StorageTek Common Array Manager(CAM) host to lose the network
connection to the array. This may, in turn, prevent out-of-band
array
management (via the network) when using CAM.
2. Contributing Factors
This issue can occur on the following platforms:
- Sun StorageTek 2510, 2530, 2540 Arrays without firmware
06.70.54.11
- Sun StorageTek 6140 Array without firmware 06.60.11.11
- Sun StorageTek 6140 Array without firmware 07.10.26.12
Note: Access to data is not
affected even if the Management Host is also a Data Host.
When a host with Sun StorageTek Common Array Manager (CAM) installed
tries to access an array through CAM, the array may send bad network
packets coming from the host (via CAM) back to the network (it forwards
the same packets on the network again). If both the CAM host and array
controllers are attached to a network
switch, the network switch stores the CAM host's MAC address
information on the switch port connected to the array, which causes the
CAM host to lose the network connection to the array.
3. Symptoms
Once the connection is lost, the "sscs list event" command may return
messages similar to the following:
("test2540" is the array name of ST2540 in this example):
$ sscs list event
:
2008-07-08 07:17:56 257 test2540 (StorageTek 2540) OutOfBand Communication Lost
2008-07-08 07:26:04 260 test2540 (StorageTek 2540) OutOfBand Communication Established
2008-07-08 07:46:03 265 test2540 (StorageTek 2540) OutOfBand Communication Established
2008-07-08 08:01:49 269 test2540 (StorageTek 2540) OutOfBand Communication Established
2008-07-08 08:11:04 272 test2540 (StorageTek 2540) OutOfBand Communication Established
2008-07-08 08:33:38 277 test2540 (StorageTek 2540) OutOfBand Communication Lost
Or, the sscs command would return a message similiar to the following:
$ sscs list array test2540
test2540: The object was not found.
Or the following error message:
$ sscs list array test2540
An unexpected internal system error occurred.
Retry the operation and then contact your Sun service representative if the error persists.
Sun StorageTek Common Array Manager (CAM) would return the following
error message when clicking on the array name link of the Sun
StorageTek 25x0 array:
(!) An error occurred during the operation to retrieve data.
The selected item was not found. It may have been deleted or modified by another session or operation.
Or:
(!) The array test2540 could not be contacted.
The operation to obtain data from the array failed.
Please look for "Lost Communication" alarm in Alarms page to get instruction.
