HP 6Gb SAS Switch for HP BladeSystem c-Class - Manual (Page 28)

Clear Configuration task
To delete all user-defined zone groups and server device bay assignments, select the active switch
in the navigation tree, and then click Clear Configuration.
IMPORTANT: If external SAS storage enclosures are connected, before clearing the configuration,
logical units associated with enclosures connected to the switch must be deleted. If a deleted zone
group has disk drives in bays that are configured as part of a logical unit, there may be I/O
problems and the controller may send error messages to the system logs about an illegal drive
movement.
Helpful hints:
•
To clear information about a single zone group, use the Delete option. For more information,
see
“Delete task” (page 27) .
Advanced Settings task
To enter these parameters, select the active switch in the navigation tree, and then click Advanced
Settings.
WARNING! Enable Multi-initiator Mode only after confirming that is it supported for use by the
storage enclosures in your solution. Enabling this mode when not supported by the devices may
result in undefined behavior.
Available parameters:
Multi-initiator
Mode Controls whether more than one BladeSystem device bay can be assigned the
same zone group.
•
Enabled—Allows a zone group to be assigned to multiple BladeSystem server
device bays. Multi-initiator mode should be enabled when shared SAS
storage enclosures, such as the P2000 G3 MSA are connected to the switch.
Enabling more than one initiator (server) to access the same storage enclosure
(zone group) is a key principle of the shared storage concept.
•
Disabled—(Default) Restricts a zone group to be assigned to only one
BladeSystem server device bay. Multi-initiator mode should be disabled when
zoned SAS storage enclosures, such as the MDS600 or D2600/D2700 are
connected to the switch. Permitting only one server to access the drives in a
zone group means that those drives will be treated as if they are directly
attached to that server.
Port Splitting
Mode Controls whether 6Gb SAS BL Switch ports can be divided into sub-ports.
Enabled—Allows a switch port to be divided into two or four separate
sub-ports. When combined with a special cable, port splitting allows you to
connect more tape devices to the switch.
