HP Logical Server Management Best Practices

provisioning for the HP 3PAR StoreServ and HP P6000/EVA. No explicit storage validation is required with SPM,

since it has returned information from the storage devices.

Figure 12 shows the “Validate” button which is available when viewing or modifying the logical storage for a specific

logical server. The typical use case would be to save the logical server definition with the desired storage

specification. The logical server software will provide a warning that the storage details need to be provided before

the logical server can be activated. Once the storage administrator has provided details regarding the allocated and

presented storage, the server administrator modifies the storage entry to include Storage WWN and LUN information

(shown in the Volume & Path Selection table of Figure 12). The “Validate” button is then used to retrieve storage

information live from the array via SMI-S (validating the Matrix OE storage definition against the actual values

defined on the array).

Figure 12: Logical server storage information has been added and validation results shown

The validation status is shown in two tables in the center of Figure 12. Note that the storage pool entry contains one

volume, and the first Validation Status table indicates the volume was successfully found (i.e., the SMI-S information

confirms the volume exits on the array). The second Validation Status table summarizes the volume properties that

have been Defined and the Actual values retrieved from the array via SMI-S instrumentation. In this case, the actual

volume has exactly the desired size and RAID level. If the volume had a different size or RAID level, the server

administrator can determine if that is acceptable or not (perhaps accepting a larger size). When using infrastructure

orchestration, the RAID levels for the storage pool entries must exactly match the RAID levels specified in the logical

disks in the service template. The host mode matches exactly; an incorrect host mode would require the server

administrator work with the storage administrator to have it corrected. The server administrator can also verify the

storage WWN information was entered correctly; an incorrectly entered Storage WWN could explain an issue with

not finding a volume, or having a volume with incompatible properties. Incorrect information can be corrected, and

the Validate button used again. Assuming the information was entered correctly, the administrator defining the
