11.0 HP StoreVirtual Storage VSA Installation and Configuration Guide (TA688-96141, September 2013)

Create additional disks
Create up to 6 additional disks for a StoreVirtual VSA. The additional disks can be added to the
StoreVirtual VSA in the CMC, while the StoreVirtual VSA is powered on.
IMPORTANT: Hot-addition of disks is not supported in VMware configurations where the storage
controller is LSI Logic SCSI. Hot-add is supported on StoreVirtual VSAs which run LeftHand OS
11.0 and higher with Paravirtual SCSI (PVSCSI) adapters.
Requirements
• Minimum disk size—5 GB
• Maximum disk size
2047 GB for vSphere Server 5.0 or 5.1, 64 TB for vSphere Server 5.5◦
◦ 2040 GB for Hyper-V for Windows Server 2008, 64 TB for Hyper-V for Windows Server
2012
• Created sequentially as follows:
vSphere Server—from SCSI 1:1 through SCSI 1:6. This assumes that the first disk has
already been created and assigned to SCSI 1:0.
◦
◦ Hyper-V—locations 1 through 6 to SCSI Controller 0. This assumes that the first disk has
already been created in SCSI Controller 0, location 0.
IMPORTANT: If you are adding disks to StoreVirtual VSAs that are already in a cluster, be aware
that the process may take more time and that the CMC does not prevent multiple storage systems
in a cluster from being taken offline. When adding a disk, the storage system is restarted and the
new disk is formatted. The format operation may take a long time to complete if the new disk is
large. New writes are then resynchronized with the other storage systems in the cluster, which can
impact performance. If it is a cluster with a single storage system, the volumes will go offline.
Further, HP recommends that you do not add another new disk until the previous disk addition has
completed. This ensures that there is no loss of quorum.
Creating the disk
1. Using either the vSphere Client, or Microsoft Hyper-V Manager, add from 1 to 6 disks to the
StoreVirtual VSA.
2. Assign each disk to the next sequential SCSI address or location.
3. Configure the disks as follows:
• vSphere Server disks as independent and persistent
• Hyper-V disks as fixed size
4. Increase memory based on the total capacity of the StoreVirtual VSA, according to the
requirements in Table 2 (page 5) .
Adding disks to RAID
A new disk appears as Uninitialized in the Disk Setup tab of the Storage configuration category.
Add the new disk to RAID, which automatically powers the disk on.
1. In the CMC, navigate to the StoreVirtual VSA.
2. Select the Storage configuration category and select the Disk Setup tab.
