Cisco MDS 9000 Family Release Notes for Storage Services Interface Image Release 4.1(3k)
Release Date: November 5, 2009
Text Part Number: OL-17791-07
This document describes the caveats and limitations for the Storage Service Interface (SSI) software for the various Cisco MDS Services Modules (SSM, MSM-18/4, and MDS 9222i module). Use this document in conjunction with the documents listed in the "Related Documentation" section.
Note Release notes are sometimes updated with new information on restrictions and caveats. Refer to the following website for the most recent version of the Cisco MDS 9000 Family Release Notes: http://www.cisco.com/en/US/products/ps5989/prod_release_notes_list.html
This document includes the following sections:
The SSI interface provides the following features:
•Network-based volume management (EMC Invista, Incipient iNSP)
•Network-assisted storage applications using SANTap
•Fibre Channel Write Acceleration (FC-WA) and SCSI flow statistics
•Network-Accelerated Serverless Backup (NASB)
•Data Mobility Manager (DMM)
•Secure Data Erase
Note As of NX-OS Release 4.1(1b), SAN-OS has been changed to NX-OS. References to SAN-OS releases before 4.1(1b) still apply.
This section describes the system requirements for Cisco MDS NX-OS Release 4.1(3) and includes the following topics:
Table 1 lists the software and hardware components supported by the Cisco MDS 9000 Family.
Determining the Software Version
Note Use the latest available software release supported by your vendor for all Cisco MDS 9000 Family products.
To determine the version of the Cisco NX-OS software currently running on a Cisco MDS 9000 Family switch using the CLI, log into the switch and enter the show version command.
To determine the version of the Cisco NX-OS software currently running on a Cisco MDS 9000 Family switch using the Fabric Manager, from the Switches tab in the information pane, locate the switch using the IP address, logical name, or WWN, and then check its version in the Release column.
To download the latest Cisco software, access the Software Center at this URL:

If SSMs are present in a Cisco MDS 9000 Family switch, these upgrades may be performed as required:
•Upgrading a previously provided package
•Upgrading the SAN-OS image
•Reformatting the SSM add-on image
If you need additional information about installing or upgrading the SSM, refer to the Cisco MDS 9000 Family Storage Services Module Software Installation and Upgrade Guide.
This section describes the new features introduced in this release. For more information about the features listed, see the documentation set listed in the"Related Documentation" section.
The SSI Release 4.1(3k) image is compatible with the Cisco MDS NX-OS Release 4.1(3a) image.
There are no new features in this release.
This sections lists limitations or restrictions associated with this release.
Configuring SSM Ports in Auto Mode
Starting with Cisco MDS SAN-OS Release 3.0(1), the SSM front panel ports can no longer be configured in auto mode. Because auto mode is the default for releases prior to Release 3.0(1), you should modify the configuration of the ports before upgrading the SAN-OS software image to NX-OS Release 4.1(3) to avoid any traffic disruption.
For information on how to reconfigure the SSM ports, refer to the "Reconfiguring SSM Ports Before Upgrading to NX-OS Release 4.1(3)" section of the Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 4.1(3a).
Before upgrading your SSI image, refer to the Cisco MDS NX-OS Release Compatibility Matrix for Storage Service Interface Images, and to Table 11 in the MDS 9000 Family Release Notes for NX-OS Release 4.1(3a). Use Table 11 to determine your nondisruptive upgrade path to Cisco MDS NX-OS Release 4.1(3).
This section lists the open and resolved caveats for this release. Use Table 2 to determine the status of a particular caveat. In the table, "O" indicates an open caveat and "R" indicates a resolved caveat.
Table 2 Open and Resolved Caveats for Cisco MDS SSI Release (4.1(3k)
DDTS Number Status
Symptom: The OCTEON data path processor (DPP) failed during PWL exception handling.
Workaround: This issue is resolved.
Symptom: Following a FIT create failure, a SANTap DVT may go into a bad state and VI creation may fail. This issue can be seen after a switch reload, when any DVT can get locked and go into a suspended state. A message like the following is displayed:
%ISAPI-SLOT1-2-MSM_CRIT: Error : VI create failed.
Workaround: This issue is resolved.
Symptom: If a host that is connected to a McData switch goes down and comes back up after a zone set activation, the zone server fails the zone check for the host and virtual target, and iSAPI rejects the host's PLOGI request. This situation occurs because of the two-second delay between the PLOGI sent from the host to the target, and an online RSCN at the host port.
Workaround: This issue is resolved.
