HP 3PAR InForm OS 3.1.1 MU1 Release Notes

Storage System or moving a large number of volumes between tiers. Dynamic Optimization first
analyzes how volumes are using physical disk space and which resources were added to the
system. It then makes intelligent, autonomic adjustments to ensure optimal volume distribution of
storage volumes.
Data movement occurs as efficiently as possible by intelligently employing the best-suited data
movement layer and applying rebalancing at a fine-grained, sub-volume level as follows, depending
on the set of new resources available within the system.

Autonomic system rebalance is supported both in InForm CLI (with the new tunesys command)
and InForm Management Console.
Additional Enhancements to Dynamic Optimization
• The tunesys command can be used to rebalance an entire HP 3PAR Storage System after
upgrades. The command can rebalance Logical Disk capacity to new nodepairs and to new
disks associated with existing nodepairs. The tunesys command can also detect and correct
mismatches between Common Provisioning Group (CPG) and Logical Disk settings.
The tunesys -cpg command option can be used to rebalance the Logical Disks within a
CPG with a single command. Instead of rebalancing individual volumes one at a time from
their original (source) CPG to a new CPG, you now have the flexibility to rebalance all volumes
within a CPG with a single command and without requiring that the volumes be moved to a
new CPG in order for the rebalancing to take effect.
Note that virtual volumes under the control of HP 3PAR Adaptive Optimization software are
not modified during system tuning.
• Rebalancing of Thin Provisioned Virtual Volumes after Controller Nodes are added to the
System now reassigns Logical Disk ownership across all nodes in the system, thereby delivering
performance optimization while minimizing ongoing remote I/O over the System backplane.
Configurable Priority for Snapshot Promote
Configurable priority for promote operation – which reverts a base volume back to an earlier
point-in-time copy - enables users to flexibly adapt the speed of rapid application recovery to meet
their business requirements. Users can set the priority level as High, Medium, or Low. This
enhancement is supported with the promote of a Virtual or Full Copy. Configurable priority levels
are also available for use with Full Copy to control the speed of creation of Full Copies of storage
volumes.
Additional Enhancements to Virtual Copy
The maximum number of Virtual Copies on an HP P10000 3PAR Storage System is 12,000,
providing users with abundant flexibility for maintaining extended libraries of efficient, disk-based,
online, point-in-time copies.
Expanded User Roles
New InForm OS user roles - Create, Basic Edit, 3PAR_AO, and 3PAR_RM - provide restricted
privilege levels, empowering less experienced administrators to own subsets of administrative tasks
safely.
