Bug Id
<SUNBUG: 6559578>

Date of Resolved Release
22-MAY-2007

Impact

Using Santricity software to manage the NAS Sun StorEdgeTek 5220/5310/5310C/5320/5320C bundled back-end storage may result in data corruption and potential loss of data.

Note: Santricity is not used to manage the back end storage ST6130 (CSM1) or ST6140 (CSM2) which was originally purchased with the Sun StorEdgeTek 5220/5310/5310/ST5320/5320c NAS heads. The RAID configuration information is stored differently than with Santricity, using the native in-band NAS RAID management GUI. Santricity will make adjustments when redistributing LUNs assigned to the NAS head (system board) resulting in possible data corruption and potential loss of data.


Contributing Factors

This issue can occur on the following platforms:

  • Sun StorageTek 5220 NAS
  • Sun StorageTek 5310 NAS
  • Sun StorageTek 5320 NAS

Note 1: This issue only occurs when using Santricity software to manage the bundled back end storage.

Note 2: A gateway license key is required to access storage not bundled with the NAS head (system board). The gateway software key removes the ability for the NAS head to manage the un-bundled storage.

Note 3: The gateway key will also prevent NAS head in-band management to the Sun StorEdge 6130/6140 arrays sold separately and attached to the NAS head with a gateway license key. Customers use the Sun CAMS software to manage the Sun StorEdge 6130/6140 arrays.

Note 4: Customers with the StorageTek Flexline products can safely use Santricity along with a NAS gateway license key because all NAS head in-band management has been disabled and Santricity was originally bundled with the product.


Symptoms

Should the described issue occur, RAID configuration information and back-end storage features adjusted by Santricity while LUNs are assigned to the NAS head will cause NAS sfs2 filesytems to go offline and require a fsck(1M) to repair.


Workaround

To avoid the described issue, do not use Santricity to manage any back-end storage attached to the NAS SE5220/SE5310/SE5310C/SE5320/SE5320C which was originally bundled with the product.

To work around this issue, use the native in-band NAS RAID management GUI stored on the NAS head compact flash. This is accessed by any web browser using the IP number assigned to the NAS.

Example using ip number 192.168.0.50:

    http://192.168.0.50
    RAID > Manage RAID

 


Resolution

Please see the Relief/Workaround section above for the final resolution to this issue.
