Working with ALUs and SLUs for vSphere VVOL

The storage systems can be integrated with a VMware® ESXi host or VMware® vCenter Server by Hitachi Storage Provider for VMware vCenter, which provides support for vSphere APIs for Storage Awareness (VASA). Snapshot and replication functions are used in storage systems that are configured with Administrative Logical Units (ALUs) and Subsidiary Logical Units (SLUs).

You can use Device Manager - Storage Navigator to create ALUs, view the ALUs and SLUs on the storage system, and unbind SLUs from ALUs.

Do not perform operations on LDEVs with the SLU or ALU attribute from Device Manager - Storage Navigator or RAID Manager. If you must perform operations on LDEVs with the SLU or ALU attribute, contact Hitachi Solution Support Center.

CautionIf you must change the configuration of LDEVs with the SLU or ALU attribute using Device Manager - Storage Navigator or RAID Manager, you must first shut down the associated virtual machines. When the virtual machine is shut down, LDEVs with the SLU or ALU attribute related to the virtual machine are unbound automatically.

If virtual machines cannot be shut down, unbind the LDEVs with the SLU attribute from LDEVs with the ALU attribute related to the virtual machines using Device Manager - Storage Navigator, and then perform the configuration change operation. For instructions, see Unbinding the SLUs from the ALUs. If you accidentally change the configuration while the virtual machine is running without first unbinding the LDEVs with the SLU attribute, contact your storage administrator.

For information about setting up and operating VMware virtualization servers, see the Hitachi Command Suite Administrator Guide.

  • Provisioning

    The advanced provisioning software products and features of the storage systems enable you to implement the appropriate provisioning strategies for your operational environment and improve performance and capacity utilization. Dynamic Provisioning allows you to reserve virtual storage capacity based on anticipated future capacity needs using virtual volumes instead of physical disk capacity, providing lower initial cost, greater efficiency, and ease of storage management.
