EqualLogic and Veeam read only volume possible fix

[mellerbeck]

Has anyone tested the below method of making a volume read only?

If it does work, I think this should be recommended for EQL customers (since the SAN can't make a volume read only)

Switch off "automount" by running mountvol.exe /N
Connect disk to Windows (do not mount the disk)
Run diskpart
Enter list volume
Enter select volume X (where X is the correct volume number from the previous command)
Enter att vol set readonly
Enter detail vol and ensure the read-only bit is set
