New to this release

Item Description
All cmdlets have been updated to support Unisphere servers running Unisphere 10.0.0 or later. These Cmdlets are used for managing storage resources such as:
  • Unisphere, PowerMaxArray
  • Volume, SLO, SRP, StorageGroup
  • Initiator, Host, HostGroup
  • Port, PortGroup
  • MaskingView, MaskingViewConnection
  • StorageGroupSnapshot, SnapshotPolicy
  • RDFGroup, RDFProtection, RDFPair
Management model classes have new fields. Most of the management model classes have been updated with new fields. Some of these fields are only applicable for newer PowerMax Arrays.
Cmdlets have been modified. Several changes were implemented to support current cmdlets such as:
  • For Get-PowerMaxArray, Ucode and TargetUcode have been renamed to Microcode and TargetMicrocode.
  • StorageGroupSnapshot cmdlets are adjusted to support -snapId instead of -generation.
  • VolumeSnapshot cmdlets are deprecated.

Known Issues and Limitations

Item Description Workaround
Storage group snapshot operations are only supported for PowerMax arrays with microcode version 5978.669.669 or higher. Generation based snapshot management restapi endpoints are deprecated and SnapId based restapi endpoints have to used instead. For lower PowerMax microcode versions, use v1.1 PowerMax module.
BW_limit property is not populated in the Host model. Unisphere restapi endpoint is not reporting the bandwidth. Use Unisphere.
