In an Azure environment, exporting a disk for Flexible Storage Sharing (FSS) may fail with "Disk not supported for FSS operation" error
For Flexible Storage Sharing, you must first export all the non-shared disks for network sharing. If your deployment setup involves JBOD type of disks, you may notice the following while exporting the non-shared disks:
The disk export operation fails with the "Disk not supported for FSS operation" error
# vxdisk export DiskName
VxVM vxdisk ERROR V-5-1-531 Device DiskName: export failed: Disk not supported for FSS operations
The checkfss disk command fails with the "Disk not valid for FSS operation" error
# vxddladm checkfss DiskName
VxVM vxddladm INFO V-5-1-18714 DiskName is not a valid disk for FSS operation
This issue occurs if a JBOD definition is not added to the disks.
Workaround:
Before exporting a disk for network sharing, add a JBOD definition on the disk.
Note:
You can add a JBOD definition to a disk only if the disk SCSI inquiry supports a unique serial number. You cannot export a disk for network sharing, if the disk's SCSI inquiry fails to have a unique serial number.
To add a JBOD definition to a disk, perform the following steps:
- Run a query on the standard disk pages (0, 0x80, and 0x83) to find the available unique serial number.
For page 0:
# /etc/vx/diag.d/vxscsiinq -d /dev/vx/rdmp/DiskName
For page 0x80:
# /etc/vx/diag.d/vxscsiinq -d -e 1 -p 0x80 /dev/vx/rdmp/DiskName
For page 0x83
# /etc/vx/diag.d/vxscsiinq -d -e 1 -p 0x83 /dev/vx/rdmp/DiskName
Following is a sample output of the command for page number 0x83 that contains the unique serial number.
------- Identifier Descriptor 1 ------- ID type : 0x1 (T10 vendor ID based) Protocol Identifier : 0x0 Code set : 0x1 PIV : 0x0 Association : 0x0 Length : 0x18 Data : 4d5346542020202069c0ae2f82ab294b834866ff... /dev/vx/rdmp/DiskName: Raw data size 32 Bytes: 0 - 7 0x00 0x83 0x00 0x1c 0x01 0x01 0x00 0x18 ........

- Note the following values from the command output in step 1:
opcode= 0x12 (18) (This is a standard opcode)
pagecode= page number that contains the unique serial number (for example, 083)
offset= byte offset where the serial number starts (For example, in the output here the offset value is 8)
length= length of the unique serial number that is provided in the Length field (24 or 0x18)
- Add JBOD definition.
# vxddladm addjbod vid=vendorid serialnum=opcode/pagecode/offset/length
For example, # vxddladm addjbod vid=MSFT serialnum=18/083/8/0x18
- Scan disks.
# vxdisk scandisks
- Verify if the JBOD definition has been added sucessfully.
# vxddladm checkfss DiskName
The command output displays a confirmation message.
