HP Insight Orchestration 6.3 User Guide

the HP Logical Server Management Best Practices white paper at HP Insight Dynamics Information
Library.
Insight Orchestration approach to storage reservation and allocation
A key step in the service creation process involves both a reservation and allocation phase for all
resources required by the service template. Following are the storage reservation and allocation
steps. The resource set that is being analyzed is always the storage pool entries defined within
Virtualization Manager.
1. Find a storage pool entry (SPE) that contains a fully matched boot disk per the logical server’s
boot disk definition.
a. If found, find one or more additional SPEs that fully match the logical server’s data disk
definitions.
2. If the boot disk reservation could not be satisfied, fall back to seeking a single SPE that fully
matches both the logical server's boot disk and data disk requirements.
3. If the boot disk reservation still cannot be satisfied, fall back to seeking a single SPE that fully
matches the logical server’s boot disk definition.
a. If found, pause the request and raise an email alert (using an Operations Orchestration
workflow) requesting manual storage provisioning for the data disk.
4. If the boot disk reservation still cannot be satisfied, pause the request and raise an email alert
requesting manual storage provisioning for both the boot and data disks.
NOTE: Whenever a request that was paused for manual storage provisioning is continued, Insight
Orchestration will re-enter the reservation algorithm, applying the same logic to satisfy both the
boot and data disk requirements for the logical server.
Using the preceding steps, the following priority is observed when trying to satisfy the storage
requirements:
1. Try: “Static” SAN volume automation through Flex-FC
2. Fall back to: “Dynamic” SAN volume automation via LUN masking
3. Fall back to: Manual storage provisioning
The storage pool entries used for the preceding algorithm are defined with Virtualization Manager
using the logical server storage pool interface. Storage pool entries can be defined and fulfilled
by a storage administrator providing appropriate details once they have created, presented, and
zoned the SAN storage volumes.
Alternatively, HP provides a solution, Storage Provisioning Manager, that enables the storage
administrator to define a catalog of pre-presented storage. Storage pool entries can be matched
against catalog entries without requiring human intervention, or requests can be viewed in the
SPM interface and manually fulfilled. If you use “Dynamic” SAN volume allocation automation,
you must ensure the authorizations for the SPM catalog entries allow LUN masking and hostmode
changes.
Configuring Storage Provisioning Manager (SPM) in Virtualization Manager
In order to make use of “Dynamic” SAN volume automation via LUN masking, it is necessary to
configure SPM for access to one or more arrays. Browse to the following URL on the CMS:
https://<cms_ip>:8001.
Select Arrays from the tree view on the left side, and click Import Arrays.
