HP 3PAR InForm OS 3.1.1 MU1 Release Notes
DescriptionItemBug ID
The error message when an empty virutal volume set was exported was not
clear. Because exporting a virtual volume set isn't a logical action this action
is no longer allowed.

Auto-choosing a LUN for a host that saw active exports using a host set
would sometimes incorrectly fail. The checks for host set exports have been
improved to resolve this issue.

the frame buffers were not released into the free buffer pool. When a large
number of these occurred, the port could run out of buffer credits and fail.
This was fixed by releasing these invalid frames correctly. This problem was
seen with a Cisco UCS server using the Palo interface card connected to
the storage system 4G port using a Brocade fabric when SAN booting
Windows 2008 R2. The Palo card driver/firmware had a defect causing
it to send incorrectly formatted Fibre Channel frames.
If a zerold was mapped to a volume offset 0, then the Inform Management
Console would display the incorrect RAID type. This has been fixed.

If an iSCSI port on a 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 has been fixed by processing the PDU correctly and sending a login
reject per the iSCSI protocol.

removing the CPG which was being used as a snap CPG before running
the command. Removal of the CPG could happen a few days later. Storage
systems with ESX clusters attached to them would have virtual host failures
because SCSI 2 reservations were not handled while system manager was
down. This has been fixed.

A fix has been implemented to correctly identify SCSI-3 reservation and
extend the check for duplicate events to include the node identifier and to
ensure that initiator list fields are populated correctly for duplicate events.

The initial design of the PD scrubber was to scrub the entire system every
seven days. Systems have gotten much larger and delays were added to

the prevent the scrubber from impacting system performance. These two
changes have resulted in many systems being scrubbed at a much slower
rate (every 60 days or more). This opens a larger window for double disk
failures. The previous design kept one chunklet per loop active and would
issue one ioctl to kernel every scan step. The new design issues one
ioctl for one chunklet of all the PDs on the node. Inside the kernel scan
steps are scheduled based on a self-implemented timer, so that the scrubbing
rate can be controlled, VERIFY operations can be spread out evenly, and
multiple PD scans can be processed at the same time.
The InForm OS kernel could leak memory when processing some SCSI
commands, as memory buffers dynamically allocated for command

processing are not freed on command completion. This leak could affect
certain commands received on LUNs to which no virtual volume is exported.
If a sufficiently large number of these commands were received, available
memory was exhausted and the node would panic. A fix has been
implemented that ensures that all memory allocated for processing of these
commands is released on command completion.
