HP 3Gb SAS Switch for HP BladeSystem c-Class - Manual (Page 43)

Modify Zone Access task
For each server device bay, use this task to grant or remove access to a zone group. This task is
displayed only if zone groups have already been created (
“Create Zone Group task” (page 37) )
IMPORTANT:
•
Depending on the BladeSystem c-Class enclosure model, server type, mezzanine slot used,
BladeSystem server device bay, and BladeSystem interconnect bay, zone groups assigned to
a server must be associated with storage enclosures connected to switch ports 1–4 or 5–8.
Failure to follow these guidelines will result in an unsupported configuration.
•
Before assigning a zone group to a server device bay, the server blades may need to be
taken offline. Restart them after completing the assignments and saving all changes in the
VSM interface.
•
For more information, see “Zoning requirements and device mappings” (page 7) .
To perform this task, expand the Blade Device Bays in the navigation tree and select a server
device bay. Then click Modify Zone Access.
From the displayed list of zone groups, check or clear the zone groups that this server device bay
can access.
NOTE:
•
The zone groups that are displayed will differ depending on the Multi-initiator mode setting:
◦ If Multi-initiator mode is Enabled, all zone groups are displayed, allowing multiple server
device bays to be assigned the same zone group (used for configurations that include
shared SAS storage enclosures or tape devices).
◦ If the multi-initiator mode is Disabled, only unassigned zone groups are displayed,
permitting a zone group to be assigned to only one server device bay. If a zone group
is already assigned to a different server device bay, it is not displayed.
•
The status of each zone group is included in the display:
◦ Assigned— Already assigned to one server device bay.
◦ Assigned Multiple—Already assigned to more than one server device bay.
◦ Unassigned—Not yet assigned to a server device bay.
◦ This is an unsupported configuration—The assignment does not obey zoning rules. For
drive-bay zone groups, the server device bay must be associated with the switch ports
used by the zone group.
•
In mixed environments that include zoned SAS storage enclosures, shared SAS storage
enclosures, and tape devices, use the displayed status information and keep detailed records
of 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.
•
If a zone group is assigned to a server that is not associated with the switch port to which the
external storage enclosure is connected, a warning message is displayed.
•
In a c7000 BladeSystem enclosure, when using a full-height blade with the P700m 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 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.
