the drive-bay zone groups and their assignments. This will help prevent accidentally assigning
drive-bay zone groups to multiple servers or to servers that are not associated with the switch
ports used by the zone group.
•
In a c7000 BladeSystem enclosure, when using a full-height blade with the P711m/P712m
controller installed in mezzanine slot 3, the zone group must be assigned to the subsumed
server device bay to allow the server to access the storage.
•
Server device bays cannot access the zone group until assigned that zone group.
•
Until the configuration is saved, the words Pending Save are displayed in the navigation
tree next to the zone. After the configuration is saved, the word Assigned is displayed.
Create and Assign Zone Group task
Zone groups allocate resources for device load balancing purposes and for selectively allowing
access to data. By first selecting the c-Class enclosure Blade Port, this task allows you to select
perform the Create Zone Group and Modify Zone Access tasks in one step.
You can create the following types of zone groups:
•
Switch-port zone groups—Group together one or more ports on the SAS BL Switch. Server
device bays assigned this type of zone group have access to the storage enclosures or tape
devices connected to the ports included in the zone. This type of zone group is for shared
SAS devices. The P2000 G3 SAS MSA and HP MSL2024, MSL4048, and MSL8096 Tape
Libraries and 1/8 G2 Tape Autoloader are examples of shared SAS devices. All LUNs in the
controller enclosure are accessible to the assigned servers, unless controlled through the storage
management utility for the controller enclosure and all tape drives in a tape device are
accessible to any server that has access to the zone group. For more information, see
“Creating
and assigning switch-port zone groups” (page 31) .
•
Drive-bay zone groups—Group together drive bays from one or more MDS600 drawers or
D2000 disk enclosures. Server device bays assigned this type of zone group have exclusive
access to the drive bays included in the zone group, as if the drives are directly connected to
those servers. This type of zone group is for zoned SAS storage enclosures. The MDS600 and
D2600/D2700 enclosures are examples of zoned SAS storage. For more information, see
“Creating and assigning drive-bay zone groups” (page 33) .
