and thus they are used for a different host (Host-B). But,

the FC driver does not completely erase the device

database entry for Host-A. Therefore, an old device entry

is present in the device database. Later, a look-up for

Host-A in the device database returns the old device entry

and further operation (for example releasing resources)

on the old entry causes a different host (Host-B) to

disconnect since the resources in the old entry are now

used by that host (Host-B).

Improved the completion times of UNMAP SCSI

commands, which results in faster format operations from

hosts.

Improved performance of SCSI UNMAP

commands.

as tunes) or a node integration could get the SYSMGR

into this state. Addressed the race condition between the

SYSMGR and kernel that causes this behavior.

condition is not handled correctly. Under rare

circumstances, this could cause node panics on busy

systems to which AIX hosts are attached. The software

issue is resolved.

This is resolved by upgrading 10G iSCSI firmware to

version 4.8.77.

The firmware issue could send incorrect TCP

segments on the network.

The 10G iSCSI firmware issue could cause

loss of iSCSI connectivity.

This results in commands stuck in the queues of the host

issue affects F class, T class systems running 3.1.1.GA,

3.1.1.MU1, 3.1.1.MU2, 3.1.2.GA releases. This is

resolved and it makes sure that a node can recover from

the memory error and report the error.

Added semaphore for apilib functions to access mcalls

in CIM. This prevents cimserver from swamping SYSMGR

by too many busy mcall requests.
