V-76-58645-585: Failed to reserve a majority of disks in cluster dynamic disk group

[Viktor_Burba]

Hi guys,

I have the issue with SCSI-3 reservation. Storage is ST6140/DS4700 with 7.50.x.x firmware, connected to the Windows 2003 server host with Emulex LPe11002 HBA (newest driver 2.20.6 and newest firmware 2.82a3)

I used utility suggested by you and here the output:

 

C:\SCSIcmd\SCSIcmd>scsicmd.exe -d4 -sscsi3_test

 

********************** SCSI-3 SUPPORT TEST ***********************************
* The SCSI-3 SUPPORT TEST performs a set of SCSI-3 PR on disk(s) specified in *
* -d option. *
* SCSICMD uses the predefined '1234567812345678' key in SCSI-3 support test. *
* *
* Make sure that the testing shouldn't be under the cluster resource. *
* *
* If SFW DMP (5.0 DDI-3/5.1 GA/5.1 DDI-1 or a newer DDI version) hasn't been *

  The disk may be been under a cluster resource or

So import as dynamic disk group works fine, but as cluster disk group does not work.

I appreciate any ideas,
Thanks in advance

From the otuput, is is saying that the harddisk is scsi-3 reserved on another host/HBA.
So it is not able to be scsi-3 reserved on this host. Is that harddisk presented on another host?

For clarification, you can run this command:
scsicmd -dX -sscsi3_reserved_status

If you are sure no other node should have it reserved / online in the cluster, you can try the following:
scsicmd -dX -sscsi3_clear
(It tries to clear SCSI-3 key and SCSI-3 reservation)

The test shows that a key was registered on the disk, the disk reserved, the disk reseravtion released, then as part of the SCSI-3 capability checking, the test is to confirm the reservation is released.

That the test has failed, suggests that SCSI-3 PGR is not supported at present.  This could mean that there are configurations on the array side that need to be made for SCSI-3 to work in this environment.

HI viktor did you followed my link. i have faced the same problem which you are facing.

Hi Viktor

You have mentiioned in your original post that you have installed latest HBA firmware and drivers. Did you also upgrade Microsoft Storport driver?
Please confirm your  SFW version and patch level as well as O/S patch level (also 32-bit or x64?)
If multiple paths: Are you using MPIO? Which DSM modules?

Also double-check Hardware Compatibility list (Here's link to SFW 5.1 HCL):
ftp://exftpp.symantec.com/pub/support/products/Storage_Foundation_for_Windows/302144.pdf

The DS4000 series is not listed under Note 3:
Note 3: Enabling SCSI-3 PGR on Your Array to Support Active/Active DMP DSM in a Cluster (MSCS/VCS)

For storage array type:
- IBM System Storage™ DS8000 Series
- IBM System Storage™ DS3400
- IBM System Storage™ SAN Volume Controller
Use:
- EnableSupportSCSI3IBMDS.reg to enable SCSI-3 PGR
- DisableSupportSCSI3IBMDS.reg to disable SCSI-3 PGR

IBM DS4000 series is listed as AP/C on page 1 of HCL.

On page 7 under Note 17 it mentions the following:

Note 17: IMPORTANT: These arrays require additional configuration steps in order to work properly with Veritas Storage Foundation for Windows. Before attempting to use any of these arrays with Veritas Storage Foundation for Windows DMP software, please contact the array hardware manufacturer for additional configuration instructions and updates. Several special settings must be enabled on these arrays to allow compatibility with DMP, including Auto Volume Transfer (AVT), also referred to as Auto Logical Drive Transfer (ADT). Specific firmware levels from the manufacturer for these arrays may also be required.
