6 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 disk 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 Storage System Administrator (HP SSA), 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: • 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 MSA 2040 SAS, P2000 G3 SAS MSA and HP MSL2024, MSL4048, MSL 8048, 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. • Drive bay zone groups-Group together drive bays from one or more MDS600 or D6000 drawers or D2600/D2700 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, D6000 , and D2600/D2700 enclosures are examples of zoned SAS storage. Key zoning configuration steps Key zoning configuration steps include: 1. Enabling/disabling Multi-initiator mode. 2. Creating zone groups. 3. Assigning zone groups to servers. 4. Capturing the configuration for safekeeping. HP strongly recommends this step, especially in single-domain configurations. For more information on zoning, see the HP 6G Virtual SAS Manager user guide, available on the HP 6Gb SAS BL Switch page of the HP Manuals website http://www.hp.com/support/manuals.
