PreviouslyPublishedAs

Product
Sun StorageTek 3510 FC Array
Sun StorageTek 6910
Sun StorageTek 6960

Bug Id
<SUNBUG: 4878805>

Date of Workaround Release
19-AUG-2003

Date of Resolved Release
20-OCT-2003

Impact

Temporary loss of Sun StorEdge 6910/6960 LUNs may occur when using sccli(1M) to manage a Sun StorEdge 3510 Fiber Channel (FC) Array from a host that also has a Sun StorEdge 6910/6960 in the configuration.

Contributing Factors

This issue can occur in the following platforms:

SPARC Platform

• Sun StorEdge 3510 FC Array without patch 113725-01

The described issue only occurs if all of the the following are true:

• sccli(1M) (version 1.2.6 or earlier) is used to manage a Sun StorEdge 3510 FC Array, and
• sccli(1M) is used on the same data host connected to the Sun StorEdge 6910/6960, and
• A Sun StorEdge 6910/6960 is connected to the same data host as the Sun StorEdge 3510 host, and
• The Sun StorEdge 6910/6960 system is running firmware 8.01 and earlier

To determine the version of "sccli", run the following command:

    # sccli -v
sccli version 1.2.6

Use the "showsc -v" command to display the firmware version of the system controller.

Symptoms

Should the described issue occur, messages similar to the following are logged to the "/var/adm/messages" file:

    May 26 10:07:33 mktgsumm fp: [ID 517869 kern.warning] WARNING: fp(1): GPN_ID for

Alternate workaround:



 Do not run sccli from a server that has Indy 69xx LUN's in it's device tree. 

 If you have no choice, use sccli out of band (over the network) to manage the 

 se3510, rather than inband. Remember, typing "sccli" with no arguments will 

 cause it to probe the entire device tree. Also, the se3kextractor script will 

 run sccli with no arguments, thus causing the issue. Inband sccli can also be

 used if it is targeted to a specific se3510 device in the device tree, see sccli

 man page.



 * Sun StorEdge 3510 FC Array with SUNWsccli T-patch T113725-01

 This tpatch is a workaround and not the long term fix. The long term

 fix will be available at a later date. Please open a PTS task to aquire 

 the tpatch. Sccli tpatch available on PTS internal links page.



 When the issue occurs, they will have to wait for the Indy Virtualization

 engines to reboot themselves. After that is complete, the LUNs should reappear

 in the fabric.
