Determining the Software Version


Note We strongly recommend that you use the latest available software release supported by your vendor for all Cisco MDS 9000 Family products.


To determine the version of the Cisco SAN-OS software currently running on a Cisco MDS 9000 Family switch using the CLI, log into the switch and enter the show version EXEC command.

To determine the version of the Cisco SAN-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.

Configuration Requirements

For Release 2.1(2m), a minimum of 5000 write acceleration buffers per SCSI flow is recommended.

Image Upgrade

If SSMs are present in a Cisco MDS 9000 Family switch, several kinds of upgrade may be performed as required—upgrading a previously provided package, upgrading the SAN-OS image, or reformatting the SSM add-on image.

New Features

There are no new features in this release.

Limitations

Release 2.1(2m) supports SCSI flow statistics in a unidirectional flow configuration; however, it does not support bidirectional flow configurations.

Compatibility Matrix

The latest Cisco MDS SAN-OS Release Compatibility Matrix for Storage Service Interface Images is available from the following Cisco Systems website.

Resolved Caveats

CSCse16033

Symptom: The Data Path Process or (DPP) fails to respond when it is configured with a bidirectional SCSI flow and a large number of Logical Unit Numbers (LUNs) for example, 3000 LUNs. This condition occurs when I/O-data buffering support is present in SSI Release 2.1(2l) and earlier on the SCSI-initiator side DPP. This condition also triggers high DPP dd utilization under heavy traffic when thousands of LUNs are serviced by a single DPP.

Workaround: Configure only unidirectional SCSI flows for SSI Release 2.1(2j) and earlier.

CSCse24825

Symptom: When the DPP software fails and is then reset, the Ternary Content Addressable Memory (TCAM) keys on that virtualization engine (for the SCSI flows managed by that DPP) are cleared, but the usage count is not reset. As a result, there is a leak in the TCAM resource on a DPP failure.

Workaround: None.

CSCse26440

Symptom: When the DPP software fails and is then reset, the SCSI-flow count for that DPP is not reset by the SCSI-flow client process on the SSM. As a result, unprovision commands entered after this event will fail.

Workaround: None.

CSCse30131

Symptom: When the DPP buffers are exhausted and an attempt is made to create a new SCSI flow, the SCSI flow client on the SSM incorrectly increases the flow count per DPP. As a result, unprovision commands entered after this event will fail.

Workaround: Avoid causing buffer exhaustion on the DPP.

Open Caveats

CSCse29496

Symptom: SCSI flow shows an unprovisioned state while in a provisioned state. Switch ports are not provisioned for bidirectional flow. This symptom may occur as a result of an un-provision followed by a re-provision of the SCSI flow feature.

Workaround: Remove the affected SCSI flows and then add them back.

CSCse34126

Symptom: Using Fabric Manager, link flaps may occur when enabling or disabling the Fibre Channel Write Acceleration (FC-WA) and SCSI Flow Statistics services at the same time. This caveat may also occur when provisioning or un-provisioning a SCSI flow service with FC-WA and/or SCSI Flow Statistics services enabled.

Workaround: Enable or disable one service at a time. If you are provisioning or un-provisioning the SCSI flow service, disable FC-WA and SCSI Flow Statistics one service at a time. After re-provisioning the SCSI flow service, enable the associated services one at a time.

Obtaining Technical Assistance

Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.

Cisco Technical Support & Documentation Website

The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do


Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.


Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
