Considerations for ESS Disks
AUTOCONFIGURE is not recommended for M8xxx disks. Confirm that this
attribute is OFF before adding M8xxx disks.
New M8xxx disks that are being used for the first time must be initialized after they
have been added.
Considerations for ESS Disks
The primary and mirror logical devices (LDEVs) in the ESS must be in different
physical array groups.
The primary LUN on the primary and backup paths must be the same.
The mirror LUN on the mirror and mirror backup paths must be the same.
For more ESS configuration information, see the Modular I/O Installation Guide or
the NonStop NS-Series Planning Guide.
