HP 6Gb SAS Switch for HP BladeSystem c-Class - Manual (Page 64)

Creating zone groups
Zone groups allocate resources for device load balancing purposes and for selectively allowing
access to data.
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
a switch-port zone group” (page 65) .
•
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 a drive-bay zone group” (page 67) . (For future use.)
Syntax <TARGET> create type=zg name=<name> [switchport=<port>]
[seb=<port:box:bay>]
Parameters Use when shared SAS storage enclosures, tape
autoloader, or libraries are connected to the switch. switchport=<port>
When using this parameter, enter the switch ports
to include in the zone groups. When more than one
switch port is to be included, separate the entries
with a comma.
seb=<port:box:bay> Use when zoned SAS storage enclosures only are
connected to the switch. When using this parameter,
enter the drive bay information. When more than
one drive bay is to be included, separate the entries
with a comma.
