Considerations for SAN boot • Dual paths to SAN/storage is recommended for all partitions - Allows online updates of switch and array firmware • Two hops or less strongly recommended • No factory installation of operating environment - nPartition and vPar definition is available and is independent of the installation of an operating system. nPartition and Resource Health Status The nPartition and resource status reveal the current health of the hardware. nPartition resources (blades and IObays) can have one of the following usage status: Resource Usage Empty Inactive Un-integrated Active Description The slot has no resource. Resource is inactive. Firmware is in the process of discovering/integrating the resource. It cannot be used for partition operations. The resource is active in the partition. 68 Booting and Resetting Partitions (nPartitions and vPars)

Considerations for Local Boot
•
Minimum configuration
—
One P2000 FC G3 can handle up to 4 partitions
—
Boot paths are not redundant
◦
You must shutdown HP Superdome 2 to update P2000 FC G3 firmware.
•
Optimal configuration
—
Create redundant boot paths to separate dual controllers on the P2000 FC G3
◦
Would support only two partitions per array
Boot from local SAN
•
HP Fibre Channel Switch(s)
—
HP StorageWorks 8/24 Base SAN Switch (AM868A) is the default switch
—
8GB switches recommended
•
Considerations for Local SAN
—
Minimum configuration:
◦
For 16 or less partitions, one dual controller P2000 can be used
—
Optimal configuration (Redundant boot paths)
◦
Array needs to be configured to expose both P2000 controllers to the partitions to
allow P2000 firmware updates
◦
The boot paths need to be in separate switches and P2000 controllers.
◦
Dual path connectivity allows switch/array firmware updates without need to take
SD2 down
◦
For more redundancy or >16 partitions a second P2000 can be used
Boot from External SAN
An unlimited number of LUNs may be presented by an external SAN.
Considerations for SAN boot
•
Dual paths to SAN/storage is recommended for all partitions
—
Allows online updates of switch and array firmware
•
Two hops or less strongly recommended
•
No factory installation of operating environment
—
nPartition and vPar definition is available and is independent of the installation of an
operating system.
nPartition and Resource Health Status
The nPartition and resource status reveal the current health of the hardware. nPartition resources
(blades and IObays) can have one of the following usage status:
Description
Resource Usage
The slot has no resource.
Empty
Resource is inactive.
Inactive
Firmware is in the process of discovering/integrating the
resource. It cannot be used for partition operations.
Un-integrated
The resource is active in the partition.
Active
