4 Zoning information HP Virtual SAS Manager (VSM) is the software application used to configure the switch, and create and manage hardware-based zone groups. These zone groups allocate resources for device load balancing purposes and for selectively allowing access to data. For planning purposes, zone groups and assignments can be pre-configured, even if servers or drives are not yet installed in BladeSystem c-Class enclosure device bays or storage enclosure drive bays. NOTE: While zoning is created and managed through the VSM, the storage is configured, formatted, and partitioned using software utilities such as the HP Array Configuration Utility (ACU), HP Storage Management Utility (SMU), and Microsoft Disk Manager. Types of zone groups There are two types of zone groups: • Drive bay zone groups-Group together drive bays, which can be chosen from one or more MDS600 storage enclosures or MDS600 storage enclosure drawers. Server bays assigned this type of zone group have exclusive access to the drive bays included in the zone group as if they are directly connected to those servers. Bay-based zoned storage environments such as those using the MDS600 use drive bay zoning. • Switch port zone groups-Group together one or more SAS ports on the switch. Server bays assigned this type of zone group have access to the controller enclosures or tape devices connected to the ports included in the zone. Tape environments and shared storage environments such as those using the MSA2000sa use switch port zoning. All tape drives in a tape device will be accessible to any server that has access to the zone group. All LUNs in the controller enclosure will be accessible to the assigned servers, unless controlled through the storage management utility for the controller enclosure. Key zoning configuration steps Key zoning configuration steps include: 1. Enabling/disabling Multi-initiator mode. 2. Creating zone groups (switch-port based or drive-bay based). 3. Assigning zone groups to servers. IMPORTANT: When assigning zone groups to servers, certain restrictions are imposed. Assigned zone groups must reside on external storage enclosures that are connected to switch ports that map to that server bay. For more information, see "Zoning requirements and device mappings" (page 39). 4. Capturing the configuration for safekeeping. HP strongly recommends this step, especially in single-domain configurations. For more information about zoning, see the HP 3G Virtual SAS Manager User Guide, available on the HP 3Gb SAS BL Switch page of the HP Manuals website http://www.hp.com/support/ manuals. 38 Zoning information

4 Zoning information
HP Virtual SAS Manager (VSM) is the software application used to configure the switch, and create
and manage hardware-based zone groups. These zone groups allocate resources for device load
balancing purposes and for selectively allowing access to data. For planning purposes, zone
groups and assignments can be pre-configured, even if servers or drives are not yet installed in
BladeSystem c-Class enclosure device bays or storage enclosure drive bays.
NOTE:
While zoning is created and managed through the VSM, the storage is configured,
formatted, and partitioned using software utilities such as the HP Array Configuration Utility (ACU),
HP Storage Management Utility (SMU), and Microsoft Disk Manager.
Types of zone groups
There are two types of zone groups:
•
Drive bay zone groups
—Group together drive bays, which can be chosen from one or more
MDS600 storage enclosures or MDS600 storage enclosure drawers. Server bays assigned
this type of zone group have exclusive access to the drive bays included in the zone group
as if they are directly connected to those servers. Bay-based zoned storage environments such
as those using the MDS600 use drive bay zoning.
•
Switch port zone groups
—Group together one or more SAS ports on the switch. Server bays
assigned this type of zone group have access to the controller enclosures or tape devices
connected to the ports included in the zone. Tape environments and shared storage
environments such as those using the MSA2000sa use switch port zoning. All tape drives in
a tape device will be accessible to any server that has access to the zone group. All LUNs in
the controller enclosure will be accessible to the assigned servers, unless controlled through
the storage management utility for the controller enclosure.
Key zoning configuration steps
Key zoning configuration steps include:
1.
Enabling/disabling Multi-initiator mode.
2.
Creating zone groups (switch-port based or drive-bay based).
3.
Assigning zone groups to servers.
IMPORTANT:
When assigning zone groups to servers, certain restrictions are imposed.
Assigned zone groups must reside on external storage enclosures that are connected to switch
ports that map to that server bay. For more information, see
“Zoning requirements and device
mappings” (page 39)
.
4.
Capturing the configuration for safekeeping. HP strongly recommends this step, especially in
single-domain configurations.
