HP 3PAR InForm OS 2.3.1 Extended MU5 Release Notes (QL226-96621, May 2013)

Table 1 Modifications to the InForm OS (continued)

In situations where there is a heavily loaded system with data-heavy snapshot with
heavily populated meta data tables, when deleting some of these snapshots, the meta

period of time. This can prevent other processes/tasks from running and can cause the background
internode comms processing to be delayed, resulting in the erroneous belief that one
of the other nodes has failed. This is resolved and it prevents the CPU from being held
for an excessive amount of time while traversing the meta data tables during snapshot
removal.
Correct a possible node down problem in the R6 CRC regenerate and re-write
processing when this action occurs as part of an R6 chunklet relocation.

It is possible to exceed the maximum number of exported LUNs by extending an
already exported VV set. This is not recommended.
Exceeding the maximum
number of LUNs.

In InForm OS 2.3.1, the showvv -cpg command only lists the base volumes belonging
to a CPG. This is modified in InForm OS 3.1.1 so that both the snapshots and the
base volumes belonging to a CPG are listed.

When a Storage System user account contains a backslash ("\") in the password
string, the VSS installer fails with the error: Unable to generate InServ Storage System
password information. Ensure that you enter the right information.

user passwords

Because of this, HP recommens that the backslash (“\”) character be not used in
passwords.
When an empty VV set is exported with auto LUN the error message LUN must be
less than 16384 is displayed. This error message is incorrect and may be ignored as
this is not a valid operation.

In rare cases, the InForm OS may see invalid intra cluster messages due to a hardware
timing bug on T-Class and F-Class Storage Systems. The InForm OS is enhanced to

messages on T-Class and
F-Class Storage Systems.

detect this situation and re-read the data to ensure only messages with correct contents
are processed.
The Virtual Volume (VV) buffer in apilib is one byte shorter when it should be 32 bytes,
including one null terminator. A VV with a name that is 31 characters long caused
the CIM server to crash. This is resolved.
Querying volume with a
31 character long name
results in CIM server and

failures.
When auto choosing a LUN for a host with active exports via a host set may fail
incorrectly.
Intermittent failure of
auto-LUN with host sets.

If the zero Logical Disk (LD) is mapped to a volume offset 0, then the InForm
Management Console (IMC) displays the incorrect RAID type.
RAID type displayed
incorrectly.

The setvv -snp_cpg command (removes the snapshot space CPG) causes the
System Manager to crash for VVs created via the createaldvv command, which

that there is no snapshot on the VV.

comes back online, the HP 3PAR storage system could not detect the RCFC link coming
online and a command had to be issued to bring the link back online. This was because
the InForm OS was not processing domain RSCNs. This is resolved by handling domain
RSCNs as well as other kinds of RSCN such as area and fabric RSCNs.
