DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following incidents:

Patch ID: VRTSvxfs 7.3.0.100

* 3923308 (Tracking ID: 3923307)

SYMPTOM:
VxFS module failed to load on RHEL7.4.

DESCRIPTION:
Since RHEL7.4 is new release therefore VxFS module failed to load
on it.

RESOLUTION:
Added VxFS support for RHEL7.4.

* 3925385 (Tracking ID: 3925384)

SYMPTOM:
During extent allocation for write operation in CFS, if error is occurred
during commit of State Map transaction, then memory leak may occur in VxFS kernel
module.

DESCRIPTION:
During extent allocation for write operation in CFS, if error is
occurred during commit of State Map transaction, then memory for locally allocated
structure are not freed up, which results in memory leak in VxFS kernel module.

RESOLUTION:
Code is modified to free up memory for locally allocated structure,
even in case of error code paths for extent allocation operation.

* 3925538 (Tracking ID: 3918285)

SYMPTOM:
During extent allocation for write operation in local mount file
system, if error is occurred during commit of State Map transaction, then count
of pending delayed allocation may remain inaccurate.

DESCRIPTION:
During extent allocation for write operation in local mount file
system, if error is occurred during commit of State Map transaction, then count
of pending delayed allocation may remain inaccurate due to wrong handling in
error code path.

RESOLUTION:
Code is modified to correct count for pending delayed allocation, if
error is occurred during commit of State Map transaction.

Patch ID: VRTSdbac 7.3.0.100

* 3925831 (Tracking ID: 3925832)

SYMPTOM:
7.3 vcsmm module does not load with RHEL 7.4

DESCRIPTION:
Since RHEL 7.4 is new release therefore vcsmm module failed to load
on it.

RESOLUTION:
The VRTSdbac package is re-compiled with RHEL 7.4 kernel (3.10.0-693.el7.x86_64) in the build 
environment to mitigate the failure.

Patch ID: VRTSamf-7.3.0.100

* 3925194 (Tracking ID: 3923100)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 7 
Update 4(RHEL7.4).

DESCRIPTION:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 
versions later than RHEL7 Update 3.

RESOLUTION:
Veritas Infoscale Availability support for Red Hat Enterprise Linux 7 Update 
4(RHEL7.4) is now introduced.

Patch ID: VRTSvxfen-7.3.0.100

Patch ID: VRTSLLT-7.3.0.100

* 3923102 (Tracking ID: 3923100)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 7 
Update 4(RHEL7.4).

DESCRIPTION:

4(RHEL7.4) is now introduced.

* 3923939 (Tracking ID: 3922320)

SYMPTOM:
Kernel panics in case of FSS with LLT over RDMA during heavy data transfer.

DESCRIPTION:
In case of FSS using LLT over RDMA, sometimes kernel may panic because of an issue in the
buffer advertisement logic of RDMA buffers. The case arises when the buffer advertisement for
a particular RDMA buffer reaches the sender LLT node earlier than the hardware ACK comes to
LLT.

RESOLUTION:
LLT module is modified to fix the panic by using a different temporary queue for such buffers.

Patch ID: VRTSvxvm 7.3.0.100

* 3924089 (Tracking ID: 3925398)

SYMPTOM:
VxVM modules failed to load on RHEL7.4.

Since RHEL7.4 is new release therefore VxVM module failed to load
on it.

RESOLUTION:
The VxVM has been re-compiled with RHEL 7.4 build environment.

* 3925243 (Tracking ID: 3913620)

SYMPTOM:
VxVM (Veritas Volume Manager) vxvmconvert utility may delete LVM
logical volume due to incorrect public offset.

DESCRIPTION:

utility, in case public offset of the disk is not aligned in multiples of 16,
the volume is lost.
