Data disk allocation
When LUNs with the required attributes are not available for a Create Service, Add servers
to group, or Add data disk to group operation, disk allocation is blocked and the infrastructure
orchestration administrator is notified.
The infrastructure orchestration administrator:
◦ Works with a SAN administrator to create the storage.
◦
Defines the storage in Matrix OE logical server management.
◦ Continues the operation.
When the operation continues, infrastructure orchestration reattempts to allocate the resources.
This pause is always necessary when infrastructure orchestration is configured to perform
manual storage provisioning and data disks are defined in the service template. It may or
may not be necessary when multi-initiator NPIV storage features or HP Storage Provisioning
Manager on-demand provisioning are enabled.
•
Add data disk to group operation
The Add data disk to group operation adds private or shared data disks to an existing
infrastructure service.
Matrix infrastructure orchestration provisions and allocates the storage to their attached servers.
When executing this operation, infrastructure orchestration:
◦ Validates the request
◦ Allocates the disks
◦ Obtains approval
◦ Power down servers
◦ Makes the new disk visible to the servers
◦ Powers up the servers
◦ Executes custom actions
◦ Sends notifications
•
Data disk scrubbing
If a Create Service operation uses manual operating system deployment, the corresponding
Delete service operation requires disks to be scrubbed manually. The infrastructure orchestration
administrator is notified and the operation pauses until the infrastructure orchestration
administrator scrubs the disks attached to the servers being deprovisioned and continues the
operation.
•
Data disk deletion
When configuring infrastructure orchestration to perform manual storage provisioning, the
infrastructure orchestration administrator is notified at the end of a Delete service operation.
The infrastructure orchestration administrator must:
◦ Edit Matrix OE logical server management storage pool entries
◦ Remove all LUNs added during the manual data disk allocation from the applicable
storage pool entries to make them available for provisioning
