Upgrading Your Cisco MDS NX-OS Software Image Send documentation comments to [email protected] Upgrading the SSI Image on Your SSM Use the following guidelines to nondisruptively upgrade the SSI image on your SSM: • Install and configure dual supervisor modules. • SSM intelligent services traffic on SSM ports is disrupted during upgrades. Fibre Channel switching traffic is not disrupted under the following conditions: - Upgrade the SSI boot images on the SSMs on the switch to a release version supported by your Cisco SAN-OS release. Refer to the Cisco MDS NX-OS Release Compatibility Matrix for Storage Service Interface Images. - All SSM applications are disabled. Use the show ssm provisioning command to determine what applications are configured. Use the no ssm enable feature command to disable these applications. - No SSM ports are in auto mode. See the "Reconfiguring SSM Ports Before Upgrading to NX-OS Release 4.2(1a)" section on page 20. - The EPLD version on the SSM is at 0x07 or higher. Use the show version module slot epld command to determine your EPLD version. Refer to the Cisco MDS 9000 Family Release Notes for Cisco MDS 9000 EPLD Images to upgrade your EPLD image. - Refer to the Cisco Data Center Interoperability Support Matrix and the "Managing Modules" chapter in the Cisco NX-OS Fundamentals Configuration Guide for information on upgrading your SSM. Upgrading a Cisco MDS 9124 or Cisco MDS 9134 Switch If you are upgrading from Cisco MDS SAN-OS Release 3.1(1) to Cisco NX-OS Release 4.2(1a) on a Cisco MDS 9124 or MDS 9134 Switch, follow these guidelines: • During the upgrade, configuration is not allowed and the fabric is expected to be stable. • The Fabric Shortest Path First (FSPF) timers must be configured to the default value of 20 seconds; otherwise, the nondisruptive upgrade is blocked to ensure that the maximum down time for the control plane can be 80 seconds. • If there are any CFS commits in the fabric, the nondisruptive upgrade will fail. • If there is a zone server merge in progress in the fabric, the nondisruptive upgrade will fail. • If a service terminates the nondisruptive upgrade, the show install all failure-reason command can display the reason that the nondisruptive upgrade cannot proceed. • If there is not enough memory in the system to load the new images, the upgrade will be made disruptive due to insufficient resources and the user will be notified in the compatibility table.

Upgrading Your Cisco MDS NX-OS Software Image
Upgrading the SSI Image on Your SSM
Use the following guidelines to nondisruptively upgrade the SSI image on your SSM:
•
Install and configure dual supervisor modules.
•
SSM intelligent services traffic on SSM ports is disrupted during upgrades. Fibre Channel switching
traffic is not disrupted under the following conditions:
–
Upgrade the SSI boot images on the SSMs on the switch to a release version supported by your
Cisco SAN-OS release. Refer to the
Cisco MDS NX-OS Release Compatibility Matrix for
Storage Service Interface Images.
–
All SSM applications are disabled. Use the
show ssm provisioning
command to determine what
applications are configured. Use the
no ssm enable feature
command to disable these
applications.
–
No SSM ports are in auto mode. See the
“Reconfiguring SSM Ports Before Upgrading to
NX-OS Release 4.2(1a)” section on page 20
.
–
The EPLD version on the SSM is at 0x07 or higher. Use the
show version module
slot
epld
command to determine your EPLD version. Refer to the
Cisco MDS 9000 Family Release Notes
for Cisco MDS 9000 EPLD Images
to upgrade your EPLD image.
–
Refer to the
Cisco Data Center Interoperability Support Matrix
and the “Managing Modules”
chapter in the
Cisco NX-OS Fundamentals Configuration Guide
<verify in doc> for information
on upgrading your SSM.
Upgrading a Cisco MDS 9124 or Cisco MDS 9134 Switch
If you are upgrading from Cisco MDS SAN-OS Release 3.1(1) to Cisco NX-OS Release 4.2(1a) on a
Cisco MDS 9124 or MDS 9134 Switch, follow these guidelines:
•
During the upgrade, configuration is not allowed and the fabric is expected to be stable.
•
The Fabric Shortest Path First (FSPF) timers must be configured to the default value of 20 seconds;
otherwise, the nondisruptive upgrade is blocked to ensure that the maximum down time for the
control plane can be 80 seconds.
•
If there are any CFS commits in the fabric, the nondisruptive upgrade will fail.
•
If there is a zone server merge in progress in the fabric, the nondisruptive upgrade will fail.
•
If a service terminates the nondisruptive upgrade, the
show install all failure-reason
command can
display the reason that the nondisruptive upgrade cannot proceed.
•
If there is not enough memory in the system to load the new images, the upgrade will be made
disruptive due to insufficient resources and the user will be notified in the compatibility table.
