Configuring P2000 G3 SAS MSA shared SAS storage enclosures
(overview)
Configuring shared SAS storage enclosures includes the following tasks, performed in sequence:
1. Enable Multi-initiator Mode. ( “Advanced Settings task” (page 28) )
2. Optional: Enable Port-splitting Mode if multiple tape autoloaders or libraries are included in
the solution. (
“Advanced Settings task” (page 28) )
3. Create one or more switch-port zone groups. ( “Create Zone Group task” (page 23) )
•
Unused switch ports can be included in a zone group.
•
Until a server device bay is assigned a zone group, it cannot access the storage.
4. Assign each zone group to each server device bay that needs access to the storage enclosures
associated with that zone group. (
“Modify Zone Access task” (page 30) )
•
All available zone groups are displayed.
•
After a zone group has been assigned to a server device bay, its status changes from
“unassigned” to “assigned”.
5. Capture the configuration for safekeeping. “Capture Configuration task” (page 36) )
6. Configure disk drives in the storage enclosure into logical storage units (LUNs) using the
management utility supported by the storage enclosure. Access to the LUNs is controlled
through mappings or other presentation methods, which grant specific server device bays to
specific LUNs.
Helpful hints
•
The HP P2000 G3 SAS MSA Array is an example of a shared SAS storage enclosure.
•
The shared SAS storage enclosure includes a RAID array controller. A RAID controller is
installed on the server, but not used for its RAID configuration capabilities.
•
Use switch-port zone groups with shared SAS storage enclosures. The entire storage enclosure
connected to that switch port is visible to all server device bays granted access to the zone
group that includes that switch port.
•
Each server device bay that needs access to the external storage must be assigned a zone
group.
◦ A server device bay can be assigned multiple zone groups.
◦ A switch-port zone group can be assigned to more than one server device bay.
◦ Unpopulated server device bays can be assigned a zone group.
•
Disks in the enclosure are configured into logical storage units (LUNs) using one of the servers
(or a designated management server) with access to the storage enclosure. Access to the LUNs
is controlled through mappings or other presentation methods, which grant specific server
device bays to specific LUNs.
