Enhancements
Using the New CLI SAN/iQ software
Release 8.0 included a new Command Line Interface that includes all SAN management functions
available for integration, automation or scripting. Install the Command Line Interface from the HP
LeftHand Management DVD.
NOTE:
To use the CLI, all storage nodes in the management group must be upgraded to 8.x. Verify the
management group version, as described in the Upgrade Guide, before using the CLI.
Name Changes
In Release 8.1, some platforms and software have been renamed. Table 1 lists the changes in platform
names, the software installation DVD, and two solution pack name changes. You may notice other
name changes throughout the product and documentation.

Fixes
•10391 —Fixed interaction between installed CLI and SAN/iQ software whereby repeated use
of a few specific commands could cause unexpected memory usage.
•10396 —Fix included to assure network card settings on the NSM 160 are consistently showing
that TCP Segmentation Offload is turned off to prevent network communication problems in some
environments.
•10398 —Fixed a rare problem in the storage server that caused it to spontaneously restart under
a combination of heavy IO load and snapshot deletes.
•10409 —Changed the display for the iSCSI gateway connection to Hostname(IP Address) instead
of just the IP address for ease of use.
•10410 —Fixed the incorrect reporting of CPU Utilization in alert notification and performance
dashboard.
SAN/iQ Release Notes6

•10415 —Added upgrade logic to attempt repair of OS array when possible during upgrade
rather than failing when encountering this rare condition.
•10417 —Added a check for verifying IP address format of the Virtual IP in the CLIQ command
modifyCluster.
•10418 —Added additional checking for a few specific CLI commands when executed from the
on-node CLI.
•10537 —Made the System Watch monitoring variable a permanent variable to assure it is not
accidentally deleted.
•10544 —Added RAID controller cache status to the CMC hardware report.
•10563 —Added a Node Summary report to the Centralized Management Console tasks menu
to provide an efficient way to gather basic storage node information from multiple nodes.
•10576 —Field imaging now can be performed with the SATA-DVD drive on the NSM 2060.
•10606 —Fixed issue that blocked upgrades and back-outs if the OS hardware RAID array is
degraded or rebuilding.
•Fixed issue where the Failover Manager and ESX Failover Manger were sharing install IDs which
could cause some confusion.
Fixes Originally Released as Patches
•9928 —The background parity initialization status has been corrected for RAID 5 and RAID 6
Logical Drives.
•10354 —Insight Manager agents are now compatible with 5.2x firmware.
•10355 —Storage nodes upgraded to SAN/iQ 8.0 that use CHAP authentication, now have
sessions displayed in the SAN/iQ 8.0 Performance Monitor.
•10394 —Eliminated interruption of logging services and addressed a service connection issue
that can lead to a short term volume availability outage.
•10518 —For the NSM2060/NSM4150 storage nodes, compress the RAID controller log to reduce
space utilization issues of the log partition.
•10534 —Fixed issue where a disconnect from the CMC occurred when the Service Console is
trying to upload large log files.
•10553 —An upgrade process does not complete properly, which can result in SAN/iQ services
not restarting as expected.
•10633 —Prevent the SAN/iQ store service from consuming excess memory in certain situations
involving large volumes/snapshots.
Installation/Upgrade Instructions
Please read the Upgrade Guide for instructions about installing Release 8.1
You can more information about HP's Lefthand products from the Manuals page of the HP Business
Support Center website:

HP LeftHand Storage Solution Release Notes 7

New in 8.0 —Utilization Computations
The formulas for computing snapshot and volume utilization have changed to more accurately reflect
the amount of space being used on the SAN.
Pre-8.0 Utilization Formulas
Utilization was computed as
(Used Space of snapshot + Used Space of Temp Space) / (Provisionable Space
of snapshot + Provisionable Space of Temp Space).
8.0 Utilization Changes
Snapshot utilization is now calculated as the used space of the snapshot divided by the provisioned
space of the snapshot:
Used Space of snapshot / Provisioned Space of snapshot.
Volume utilization is calculated as the used space of the volume divided by the provisioned space of
the volume:
Used Space of volume / Provisioned Space of volume.
For thinly provisioned volumes, utilization will vary because the volume “autogrows”as data is written
to it. As utilization approaches 100%, the volume will autogrow and the utilization percent will
decrease. This pattern of increasing utilization, autogrow, and decreasing utilization repeats over
time and volume use.
Compatibility/Interoperability
For a complete list of supported SAN/iQ software releases and application software compatibility,
see the Customer Resource Center at www.LeftHandNetworks.com-> Services & Support->Software
Downloads->Products-> Compatibility Lists.
Version Requirements
To upgrade to Release 8.1 SAN/iQ software, the storage nodes must be at version 7.0 or later. If
the storage nodes are at a lower version, please contact Customer Support for access to the interim
upgrade files. Refer to HP technical supportfor customer support contact information.
If you are upgrading to 8.1 from 7.x only, you must first ensure that the appropriate patches and
LSMD have been applied. See the Upgrade Flowcharts in the Upgrade Guide.
Required version of the Microsoft iSCSI Software Initiator - Version 2.08 (or greater)
Mixed SAN/iQ Software Versions in Clusters
Clusters can accommodate storage nodes running different versions of the SAN/iQ software. However,
you can only add storage nodes running a later software version to a cluster running an earlier
software version. For example, you can add a storage node running the 8.1 version software to a
cluster currently running the 7.0.0x software. You cannot add a storage node running 7.0.0x software
to a cluster running 8.1 software.
If you partially upgrade a cluster, the cluster will continue to run on the earlier software version until
the entire cluster is upgraded.
