693.el7.x86_64)
in the build environment to mitigate the failure.

* 3901580 (Tracking ID: 3896877)

versions later than RHEL7 Update 2.

RESOLUTION:

3(RHEL7.3) is now introduced.

Patch ID: VRTSamf-7.1.0.200

* 3929360 (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.

* 3899850 (Tracking ID: 3896877)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 7 Update 3
(RHEL6.8).

DESCRIPTION:
Veritas Infoscale Availability does not support RHEL versions later than RHEL7
Update 2.

RESOLUTION:
Veritas Infoscale Availability support for Red Hat Enterprise Linux 7 Update 3
(RHEL7.3) is now introduced.

Patch ID: VRTSvxfen-7.1.0.500

* 3928663 (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.

* 3901438 (Tracking ID: 3896877)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 7 Update 3
(RHEL6.8).

DESCRIPTION:
Veritas Infoscale Availability does not support RHEL versions later than RHEL7
Update 2.

RESOLUTION:
Veritas Infoscale Availability support for Red Hat Enterprise Linux 7 Update 3
(RHEL7.3) is now introduced.

* 3879189 (Tracking ID: 3878333)

SYMPTOM:
With I/O fencing in SCSI-3 mode, if you enable the auto-refresh feature on the 
CoordPoint agent, then I/O fencing fails to automatically refresh registrations 
on the coordination points. This results in vxfen group to remain in faulted 
state.

DESCRIPTION:
Even to refresh registration on coordination disks, the vxfenswap script 
expects inputs about coordination disk groups from the CoordPoint agent. The 
CoordPoint agent does not provide this information to the vxfenswap script.
This causes the vxfenswap script to fail and the vxfen group remains faulted 
until it is manually cleared.

RESOLUTION:
The I/O fencing program is modified such that in SCSI3 mode fencing, the 
vxfenswap script does not explicitly require the coordination disk group 
information for refreshing registration keys on disks.

Patch ID: VRTSgab-7.1.0.500

* 3929359 (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.

* 3901437 (Tracking ID: 3896877)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 7 Update 3
(RHEL6.8).

DESCRIPTION:
Veritas Infoscale Availability does not support RHEL versions later than RHEL7
Update 2.

RESOLUTION:
Veritas Infoscale Availability support for Red Hat Enterprise Linux 7 Update 3
(RHEL7.3) is now introduced.

* 3893802 (Tracking ID: 3893801)

SYMPTOM:
In large clusters, a node join for a gab port gets stuck.

DESCRIPTION:
When a node joins a cluster, a few GAB directed messages might be
delivered in the incorrect order to the GAB clients. This incorrect 
message order is because of a bug in code where the messages are added to the
GAB delivery queue in incorrect order.

RESOLUTION:
The program is modified to ensure that during a node join scenario,
the GAB directed messages are inserted in the various GAB queues in the correct
order.

Patch ID: VRTSllt-7.1.0.700

SYMPTOM:
