Bug Id
<SUNBUG: 6583779>

Date of Workaround Release
04-SEP-2007

Date of Resolved Release
18-OCT-2007

Impact

Sun StorageTek 6130/6140/6540 and Sun StorageTek Flexline 240/280/380 arrays using either Common Array Manager (CAM) or SANtricity, may experience loss of network access from Management Host. Once the array network connection stops working, it is no longer possible for the Management Host to monitor or manage the array.

Access to data is not affected even if the Management Host is also a Data Host.


Contributing Factors

This issue can occur on the following platforms:

  • Sun StorageTek 6130 without array firmware 06.19.25.16
  • Sun StorageTek 6140 without array firmware 06.19.25.16
  • Sun StorageTek 6540 without array firmware 06.19.25.16
  • Sun StorageTek Flexline 240 without array firmware 06.19.25.26
  • Sun StorageTek Flexline 280 without array firmware 06.19.25.26
  • Sun StorageTek Flexline 380 without array firmware 06.19.25.26

with repeated gathering of supportData in Common Array Manager (CAM) or supportdata in SANtricity.


Symptoms

If the described issue occurs, from CAM's Browser User Interface Storage System Summary page, the Health of the array will say "Lost Communication" and it will not be possible to manage or monitor the array. In SANtriicty, you will be unable to connect. Attempts to ping either array controller will be unsuccessful. Attempts to use the Serial Service Interface appear to be unaffected.


Workaround

For immediate relief from this issue, power cycle the array.

If running any monitoring scripts in addition to the services offered by CAM or SANtricity that specifically call out the collection of the array supportData (see below), stop using them until a final resolution can be provided:

CAM - <fms_home>/bin/supportData -d <arrayname> -p <directory> -o <file_name>

    Solaris - fms_home = /opt/SUNWsefms
    Linux - fms_home = /opt/sun/cam/private/fms
    Windows - fms_home = C:\Program Files\Sun_Microsystems\StorageTek_Mgmt\Component\fms

SANtricity - <SMcli_home>\SMcli -n <arrayname> -c "save storageArray supportData file=\"supportdata.zip\";"

    Windows - SMcli_home = C:\Program Files\StorageManager\client
    Solaris/Linux - SMcli_home = /opt/SM9/client

A binary fix is available through normal support channels.


Resolution

This issue is addressed in the following releases:

  • Sun StorageTek 6130 with array firmware 06.19.25.16 or later
  • Sun StorageTek 6140 with array firmware 06.19.25.16 or later
  • Sun StorageTek 6540 with array firmware 06.19.25.16 or later
  • Sun StorageTek Flexline 240 with array firmware 06.19.25.26 or later
  • Sun StorageTek Flexline 280 with array firmware 06.19.25.26 or later
  • Sun StorageTek Flexline 380 with array firmware 06.19.25.26 or later

The firmware versions listed above are provided as part of the Sun StorageTek Common Array Manager 6.0 release bundle.

Internal Comments


This issue can be verified by running "inetstatShow" from the debug port. In the output you should see a "LISTEN" state on TCP Proto for port 2463 in order for CAM or SANtricity to manage the array. If this port is not listening, you have encountered the issue.

For CAM users, you will not be able to load the 6.19.25.14 firmware using the BUI, you will have to use "/opt/SUNWstksm/bin/csmservice" with the "-s" option.



For SANtricity users, there is no need to reload the NVSRAM file, only the 6.19.25.24 firmware.



Until the next version of CAM/SANtricity is released with this firmware, open a task to PTS to obtain it.
