The recommended maximum size of a single Dynamic Optimization (tune) request is
approximately 160TB. Tunes larger than this may cause a sysmgr restart. This can
affect tunevv -cnt operations with a large number of Virtual Volumes.

If an iSCSI port on an Storage System received a non-login-related iSCSI PDU from
an initiator before the login command sequence was completed, the InForm OS kernel

could panic due to accessing an uninitialized pointer. This is resolved by processing
the PDU correctly and sending a Login reject as per the iSCSI protocol.
This is resolved in InForm OS 3.1.1. There are no pre-configured community strings
on newly installed systems. As a workaround for 2.3.1.MU5, the default password
can be removed with removesnmppw -r if showsnmppw -rindicates its set.

The createhost command for an iSCSI host does not allow placing the host into a
domain set. To perform this operation, a separate movetodomain operation is needed
after using createhost.

This addresses an issue in earlier software releases where Emulex HBA ports configured
in host/fabric mode could be switched to initiator mode after node replacement.

Incorrect iptables rules are being added due to a timing issue during startup. The
timing issue is resolved.

Under certain circumstances, removing a VLUN then immediately creating a new
VLUN to the same host and LUN number would fail with the error message: lumap
should be lm_type_loop only. This is resolved and the LUNs are created correctly now.
Resolved failure in rapid

It is possible to incorrectly export some VV types (for example, the target of a physical
copy operation) using VV sets.

LUNs must be manually chosen for these hosts, or a starting LUN of 1 chosen for
automatic assignment.

When a vvcopy task is running, it incorrectly logs Task Stopped events every few
seconds. These events can be ignored.

as UNKNOWN instead of the VV name.
