Except the port used by OS drive, I have 4 more SATA ports in this server. I had two 4TB drives before, they were almost full so I plan to migrate them to larger disks. Assuming the 4TB disks are 4A and 4B. here was my plan:
(1) Install a new 6TB drive (6A)
(2) Migrate from 4A to 6A
(3) Wait for retention period to pass, retire 4A
(4) Install the second new 6TB drive (6B)
(5) Migrate from 4B to 6B
(6) Wait for retention period to pass. retire
4B
I used MigrateDatasourceDataFromDPM.ps1 to do the migration. However something went wrong during step (2), the longest retention period in all of my protections is 10 days, but disk 4A has not been cleaned up after 90 days. The even worse thing thing is, disk 4A is still being used for new protection groups that I creates !
So it ends up with:
port 1: 4A: 1.63 TB used, 2.06 TB Free (55% unallocated)
port 2: 4B: 2.65 TB used, 1.07 TB free (28%
unallocated)port 3: 6A: 4.87 TB used, 720GB free (12%
unallocated)
port 4: not used
As you can see, from all existing three disks
I do not have space to entirely free up either disk 4A or 4B, I have to use the last available port to add in disk 6B. But I want to make sure that I migrate both 4A and 4B to it (1.63TB + 2.65TB = 4.28 which it is capable of taking).
Can I run MigrateDatasourceDataFromDPM.ps1 from 4A to 6B and immediately again from 4B to 6B? If not, how do I resolve
this drama ? Eventually I only want to leave disk 6A and 6B.
