Problem

 

For disks that are a part of Veritas Dynamic Diskgroup, some of the disks in the diskgroup report as Missing. An UnknownDg is seen in Veritas Enterprise Administrator (VEA) that contains a list of disks reporting as Foreign.

 

An attempt to perform a "Merge Foreign Disk" fails 

Error Message

 

Attempting a "Merge Foreign Disk" from VEA, would give below error

Cause

 

The disks reporting as Foreign are write protected.

Solution

 

1. Confirm that the disks are actually write protected.

 

To do so, run the SCSICMD tool (https://www.veritas.com/support/en_US/article.100021389) as below

scsicmd -d<harddiskno> -sscsi_reserved_status

Eg: If  Harddisk21 is reporting as Foreign and the above error occurs when trying a "Merge Foreign Disk" operation, the SCSICMD command will be

scsicmd -d21 -sscsi_reserved_status. 

Below is the output to confirm it is write protected. 

 

2. The issue stands outside Veritas scope and would need Storage team to be engaged to remove the write protection. 

 

3. Once write-protection is removed, attempt a "Merge Foreign Disk " operation again and it should now complete.
