I'm reading up on symm optimizer virtual lun migration. I have found some documents saying 3+1 and 7+1 migrations can take place across disk groups of same Raid type. We are using a DMX 3 for testing running 5772 code. I cant see where it states 3+1 to a 7+1 config is supported and the other way around.
Does it allow migrations of same raid type to differenly raid sets. For instance. move a 8GB lun from R5 3+1 to a R5 7+1 lun?
VLUN migration is available in Symmetrix VMAX running Enguinity 5874 and later. And here are some restrictions in virtual LUN migration:
Restrictions ◆ You cannot migrate protected devices to an unprotected protection type. Migrations of unprotected source devices to unprotected target are supported.
◆ You cannot migrate to the same protection type (RAID 5 (3+1) to RAID 5 (3+1) and the same disk group number (disk group 1 to disk group 1). The desired protection type or disk group number must be different from what exists on the source devices.
◆ Device types not supported: • VDEVs (TimeFinder Snap) • Thin devices • DATA devices • Vault devices/
