Use the CLI command showvv –pol to determine the current policy on virtual volumes.

32-Bit Libraries Needed for 64-Bit Red Hat Enterprise Linux 6.1 to Run a CLI Client

(Bug 63679)

The 64-bit OS version of Red Hat Enterprise Linux 6.1 (RHEL) may require the installation of

compatible 32-bit libraries prior to installing this CLI client patch. The CLI installer is a 32-bit linux

binary created by InstallAnywhere, which assumes the necessary 32-bit compatibility libraries are

installed. Listed below are two Workaround options:

Workaround — During the RHEL 6.1 64-bit system installation, include the Compatibility Libraries

when you customize the software to be installed on the system.

Workaround — If the RHEL 6.1 64-bit system is already installed and the 32-bit libraries were not

included, then manually install the following 32-bit rpm packages: glibc, libXext and libXtst.

The rpm packages can be found on the RHEL install CD in the Packages directory.

32-Bit Library Example:

# rpm -Uvh libXau-1.0.5-1.el6.i686.rpm libxcb-1.5-1.el6.i686.rpm

libX11-1.3-2.el6.i686.rpm nss-softokn-freebl-3.12.9-3.el6.i686.rpm

glibc-2.12-1.25.el6.i686.rpm libXi-1.3-3.el6.i686.rpm

4Gb/s 2-Port adapter Issue

The 4Gb/s 2-port Fibre Channel Adapter firmware does not detect a loss of sync when the host

reboots and has older adapters (ex: QLA2342) that do not turn off the laser.

Workaround - None.

Downgrade Issues

The following are downgrade issues for InForm OS release 3.1.1.

Issues Preventing Downgrades from InForm OS release 3.1.1 to InForm OS release 2.3.1

These issues prevent an HP 3PAR Storage System from downgrading from InForm OS release 3.1.1

to InForm OS release 2.3.1.

• Read/Write snapshots with zero detect policy - InForm OS 2.3.1 I/O code paths do not support

Read/Write snapshots on which zero detect or write-same-zero driven space optimization is

performed. Before downgrading from InForm OS 3.1.1 to InForm OS 2.31, you must remove

all Read/Write snapshots that have zero detect policy enabled or that have space optimization

exception entries created by zero detect or write-same-zero.

• Users with Extended Roles - InForm OS releases prior to 3.1.1 do not support the users with

extended roles features. Before downgrading from InForm OS 3.1.1, you must remove all

users with extended roles.

• Read/Write Snapshots admitted to Remote Copy Groups - If read/write snapshots are admitted

to Remote Copy groups in InForm OS 3.1.1, downgrades to InForm OS 2.3.1 are not allowed.

Before downgrading from InForm OS 3.1.1 to InForm OS 2.3.1, ensure that all read/write

snapshots are removed from Remote Copy groups.

Issues Preventing Downgrades from InForm OS release 3.1.1 to InForm OS release 2.2.4

These issues prevent an HP 3PAR Storage System from downgrading from InForm OS release 3.1.1

to InForm OS release 2.2.4.

• Dual SD Space - As of InForm OS 2.3.1, Thin Provisioned virtual volumes can have two Snap

Data (SD) volumes. This is not a supported feature in previous InForm releases. Prior to a
