Software Download Process Selecting the Correct Software Image for an MDS 9100 Series Switch The system and kickstart image that you use for an MDS 9100 Series switch depends on which switch you use, as shown in Table 8.
Upgrading Your Cisco MDS NX-OS Software Image NPE Software Images No payload encryption (NPE) images are available with some releases of Cisco MDS NX-OS Release 5.2(x) software. The NPE images are intended for countries who have import restrictions on products that encrypt payload data. To differentiate an NPE image from the standard software image, the letters npe are included in the image name as follows: • m9500-sf2ek9-kickstart-mz-npe.5.2.2.bin • m9500-sf2ek9-mz-npe.5.2.2.
Upgrading Your Cisco MDS NX-OS Software Image fabric mode, you cannot subsequently perform a nondisruptive software downgrade from NX-OS Release 5.2(1). For additional information, see the “Downgrading Guidelines Specific to NX-OS Release 5.2(8b)” section on page 20. • Ensure that you have a Supervisor-2A module (DS-X9530-SF2A-K9) installed in a MDS 9500 Series switch if you plan to use the Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) (DS-X9708-K9).
Upgrading Your Cisco MDS NX-OS Software Image The network can now run in IVR-NAT mode. General Upgrading Guidelines Follow these general guidelines before performing a software upgrade: • Review the nondisruptive upgrade path to Release 5.2(8b) in Table 11. • Install and configure dual supervisor modules before the upgrade. • Issue the show install all impact upgrade-image CLI command to determine if your upgrade will be nondisruptive.
Upgrading Your Cisco MDS NX-OS Software Image Table 11 Nondisruptive Upgrade Path to Cisco MDS NX-OS Release 5.2(8b) Current Release Nondisruptive Upgrade Path and Ordered Upgrade Steps NX-OS: Release 5.2(1), 5.2(2), 5.2(2a), 5.2(2d), 5.2(6), 5.2(6a), 5.2(6b), 5.2(8), 5.2(8a) Upgrade directly to NX-OS Release 5.2(8b).

Downgrading Your Cisco MDS SAN-OS Software Image Downgrading Guidelines Specific to NX-OS Release 5.2(8b) The following guidelines apply to a downgrade from Cisco MDS NX-OS Release 5.2(8b): • Cisco NX-OS Release 5.2(8b) and later releases support IDLE as a fill word for the switchport fill-pattern command. Releases earlier than Release 5.2(8b) supported only the ARBFF fill word. As a result, when you downgrade from Cisco NX-OS Release 5.
Downgrading Your Cisco MDS SAN-OS Software Image – no switchport mode st to negate the SPAN target port mode for the SPAN target port General Downgrading Guidelines Follow these general guidelines before you perform a a software downgrade: • Issue the system no acl-adjacency-sharing execute command to disable ACL adjacency usage on Generation 2 and Generation 1 modules.

Limitations and Restrictions Maximum Number of Zones Supported in Interop Mode 4 In interop mode 4, the maximum number of zones that is supported in an active zone set is 2047, due to limitations in the connected vendor switch. When IVR is used in interop mode 4, the maximum number of zones supported, including IVR zones, in the active zone set is 2047. InterVSAN Routing When using InterVSAN Routing (IVR), it is recommended to enable Cisco Fabric Services (CFS) on all IVR-enabled switches.
Limitations and Restrictions Proceed with the upgrade to NX-OS Release 4.2(1b). If you upgrade before disabling SSH and creating RSA version 2 keys, follow these steps: Step 1 Open a Telnet session and log in through the console. Step 2 Use the no feature ssh command to disable SSH. Step 3 Use the ssh key rsa 1024 command to create RSA version 2 keys. Step 4 Use the feature ssh command to enable SSH. CFS Cannot Distribute All Call Home Information In MDS NX-OS Release 4.
Limitations and Restrictions • DS-C9124-K9, Cisco MDS 9124 Multilayer Fabric Switch, if NPIV is enabled and the switch is used as the NPV core switch Trunking F ports, trunking F port channels and regular F port channels are not supported on the following MDS 9000 components: • DS-X9016, Cisco MDS 9000 2-Gbps16-Port Fibre Channel Switching Module • DS-X9032, Cisco MDS 9000 2-Gbps 32-Port Fibre Channel Switching Module • DS-X9032-14K9, Cisco MDS 9000 14/2-Port Multiprotocol Services Module (MPS-14/2)
Limitations and Restrictions Running Storage Applications on the MSM-18/4 The Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4) does not support multiple, concurrent storage applications. Only one application, such as SME or DMM, can run on the MSM-18/4 at a time.
Limitations and Restrictions • Buffer Credits: default value When you configure port mode to auto or E on a Generation 3 module, one or two of the ports will not come up for the following configuration: • Port Mode: auto or E for the first half of the ports, the second half of the ports, or for all of the ports • Rate Mode: dedicated • Buffer Credits: default value When you configure port mode to auto or E for all ports in the global buffer pool, you need to reconfigure buffer credits on one or mor
Caveats This configuration ensures that the devices connected to the Cisco MDS 9000 switch can be seen in the name server database on the Brocade switch. Caveats This section lists the open and resolved caveats for this release. Use Table 17 to determine the status of a particular caveat. In the table, “O” indicates an open caveat and “R” indicates a resolved caveat.
Caveats Table 17 Open Caveats and Resolved Caveats Reference (continued) DDTS Number NX-OS Software Release (Open or Resolved) NX-OS Software Release (Open or Resolved) 5.2(8a) 5.2(8b) — O Severity 6 CSCue31727 Resolved Caveats • CSCub47799 Symptom: Zone crash or multiple switch reload occurs after a device-alias commit. Condition: This issue applies to the following NX-OS versions or platform combinations only: – The Cisco MDS switches running MDS NX-OS Release 5.2(6), 5.2(6a), 5.2(6b), 5.
Caveats • CSCug76835 Symptom: Cisco MDS DS-X9232-256K9 and DS-X924256K9 switching modules attempt to log unnecessary EEM events to syslog on the supervisor. Condition: This issue only includes reporting hardware events such as interrupts. Workaround: This issue is resolved. • CSCub93429 Symptom: On Cisco MDS 9000 Family switches, CLI help (?) does not list all the available commands, keywords, and arguments for a user. Also, the tab key command completion does not work.
Caveats • CSCtw64713 Symptom: Occasionally, a 10-G ISL between a 32-port 8-Gbps Advanced Fibre Channel Switching Module (DS-X9232-256K9) or a 48-port 8-Gbps Advanced Fibre Channel Switching Module (DS-X9248-256K9) and an older generation Cisco MDS 9000 module can take a long time to come up. The link can go into an error-disabled state. Workaround: None.
Caveats • CSCtz40745 Symptom: A “VSAN down” trap is sent for VSAN 4094 when a trunk port goes down even though the VSAN is not configured on the trunk. This symptom might be seen only when a link down occurs on an E, TE, or TF port. Workaround: Ignore the trap. • CSCua09712 Symptom: Communication errors that occur during the master key rekey are not handled gracefully. Workaround: None. • CSCtz84847 Symptom: When creating a cluster, key management servers are not listed in the drop-down list.
Caveats • CSCug67068 Symptom: On Cisco MDS 9148 and MDS 9134 switches, an attempt to overwrite a file fails with the following error: Permission denied Condition: This issue occurs if a previous attempt to copy to a file with the same name failed. Workaround: None. • CSCuh37423 Symptom: After changing the device alias configuration, the I/O Accelerator (IOA) flows remain unchanged until the reactivation of the zone set.
Related Documentation • CSCuh88074 Symptom: Ports of a replaced switching module that are part of an existing port-channel cannot be added as members of another port-channel. Condition: This situation occurs when you replace the Cisco MDS 9000 Generation 2 module with a Generation 3 module or replace a Generation 3 module with a Generation 4 module. Workaround: After the replacement of the switching module, you must configure the same ports to the same port-channel.
