HP CloudSystem Matrix How-To Guide: ESXi Cluster Provisioning

Adding storage to an IO VM Cluster service by adding a volume to a pre-existing SPE requires taking the following

steps:

1. Carve the storage on the SAN storage array.

2. Present the storage on the SAN storage array.

3. Add the volume to the SPE if it is not already defined in the SPE.

4. Mark the volume as "Ready" in the SPE.

5. Perform the IO disk add.

NOTE: Zoning is the same as all other volumes in the SPE, so it does not need to be modified.

The disk add operation will update IO to reflect the added disk. The 10_ConfigureVMHostDataStore_group_end

workflow attached to the Add Data Disk End actions causes the VM host to rescan the SCSI bus and creates a

data store for the volume in vCenter.

Predefined SPM-managed static storage pool entries

Storage Provisioning Manager can manage a predefined SPE to automate the presentation of the storage on the

SAN storage array. (For more information, see the HP Storage Provisioning Manager User Guide at

http://www.hp.com/go/matrixoe/docs.) Volumes must still be properly carved and zoned. The IO disk add process

directs the presentation of the volume. Adding an SPM-managed volume does not introduce a new SPE to the blade,

and no Virtual Connect profile deactivation is required (or the associated reboot). After the storage becomes

available to the blade, the OS can rescan the SCSI bus and begin using the new volumes.

The disk add operation will instruct SPM to present the storage to the host initiator port that WWN defined in the

SPE and update IO to reflect the added disk. The 10_ConfigureVMHostDataStore_group_end OO workflow

attached to the Add Data Disk End actions causes the VM host to rescan the SCSI bus and creates a data store for

the volume in vCenter.

SPM-managed autocarved storage pool entries (HP Matrix Operating

Environment 7.1 and later)

IO can be configured to use a properly configured Storage Provisioning Manager to automatically carve, present,

and zone storage. (For more information, see the HP Storage Provisioning Manager User Guide and the HP Matrix

Operating Environment 7.0 Infrastructure Orchestration User Guide at http://www.hp.com/go/matrixoe/docs.) The

carving, presentation, and zoning of the volume are directed by the IO disk add process. Adding an SPM-managed

on-demand volume does not introduce a new SPE to the blade, and no Virtual Connect profile deactivation is

required (or the associated reboot). After storage becomes available to the blade, the OS can rescan the SCSI bus

and begin using the new volumes.
