Introduction
These release notes describe the features and known issues for the Cisco High-Performance Subnet Manager (HSM) 1.2.1.
System Requirements
This section describes the system requirements for this software release.
Cisco supports HSM with all existing Cisco InfiniBand HCAs, Cisco InfiniBand switches, and Cisco Ethernet and Fibre Channel gateways.
HSM requires that Cisco OFED 1.1 or higher, or Cisco Commercial InfiniBand 3.2.0 host drivers are installed before installing HSM.
Determining the Software Version
If InfiniBand drivers are already installed on the host, they may be installed in one of several locations.
To determine the version of the Cisco InfiniBand host drivers, log in to the host and enter the following commands at the shell prompt. If the first command produces output, the Cisco Commercial InfiniBand host drivers are installed. If the second or third commands produce a version number, OFED host drivers are installed.

To verify that you are running the latest available release, compare your version against the latest version on the Cisco support website. After registering your product, you should have received a username and password that grant you access to this site.
Old and new HSM releases can be used in the same InfiniBand fabric, although InfiniBand subnet manager synchronization will not occur between HSM 1.2.1 and HSM releases earlier than 1.2.
For general information about upgrading to a new software release, see the Installing the Cisco High-Performance Subnet Manager section in the Cisco High-Performance Subnet Manager for InfiniBand Server Switches document.
New and Changed Information
HSM 1.2 is a major release that introduces significant new features and documentation. It includes the following changes:
•
•
•
•
•
•
•
•
Changes From HSM 1.2 (build 152) to HSM 1.2.1 (build 161)
This section describes the new features and resolved caveats since the HSM 1.2 release.
Note
General
•
The maximum number of concurrent CLI sessions has been increased from 3 to 20, and has been made tunable via command-line parameters.
InfiniBand
•
Support has been added for correctly managing InfiniBand fabrics that include the Cisco SFS 3504 Multifabric Server Switch.
•
Support has been added for correctly managing InfiniBand fabrics that include the Dell PowerEdge M1000e modular blade chassis.
•
Support has been added for excluding IB ports that are down from the Performance Manager output. This feature adds a new config pm monitor downed-port-access CLI command.
Note
•
A problem has been fixed where the Performance Manager reported incorrect cumulative counters on the Cisco SFS 7012/7012D/7024/7024D Server Switch and the Cisco M SFS7000E Switch.
•
A problem has been fixed where the Subnet Manager might not correctly program a switch that was reset while an InfiniBand fabric sweep was in progress.
•
A problem has been fixed where the Subnet Manager might fail if an OFED host failed to return a response InfiniBand packet for a management transaction.
•
A problem has been fixed where the Subnet Manager would become temporarily unresponsive while processing a large number of multicast groups.
•
A problem has been fixed where the portmask output from the show mft CLI command was incorrect.
•
A problem has been fixed where the Subnet Manager log information was not clear when subnet manager synchronization failed due to incompatible Subnet Manager versions.
•
A problem has been fixed where the Subnet Manager did not properly handle PathRecord and MultiPathRecord SA queries that specify the tclass in the request.
•
A problem has been fixed where the Subnet Manager would become temporarily unresponsive while processing SL-to-VL mapping table and VL arbitration table CLI commands.
•
A problem has been fixed where the Subnet Manager log information was not clear when the Subnet Manager failed to start due to incorrect command-line arguments.
•
A problem has been fixed where the Subnet Manager would fail if a node M_Key was not set properly.
•
A problem has been fixed where the Subnet Manager might not correctly synchronize when using multiple standby Subnet Managers.
Changes From HSM 1.1 (build 99) to HSM 1.2 (build 152)
This section describes the new features and resolved caveats since the HSM 1.1 release.
General
•
Support has been added for running HSM on OFED 1.2 or OFED 1.1.
InfiniBand
•
Support has been added for Switched Port Analyzer (SPAN), also known as port mirroring. This feature adds a new span CLI command that enables users to mirror the packets ingressing one switch port to another port on that switch. By connecting an IB analyzer, users can capture and view the mirrored packets. Note that there are several restrictions to SPAN at this time:
–
–
–
•
Support has been added for configuring low-level Quality of Service (QoS). This feature adds new CLI commands to configure SL-to-VL mapping tables and VL arbitration tables.
•
Support has been added for IB SM synchronization between one master SM and two standby SMs. Previously, only one standby was allowed.
•
A problem has been fixed where the path MTU and rate returned in a PathRecord query could be set incorrectly, resulting in low throughput, especially for paths traversing DDR IB links.
•
A problem has been fixed where a deadlock could arise caused by a temporary InfiniBand packet credit loop while rerouting a network. The solution was to change the default packet lifetime from infinite (never discard) to approximately one second.
•
Support has been added for disabling IPoIB on an InfiniBand partition. This feature can be used to increase security on the default IB partition FFFF. Note that in TopspinOS 2.9.0 the mgmt-ib management InfiniBand interface cannot be used with a non-default IB partition.
•
Support has been added for routing around InfiniBand components that need maintenance. This feature adds a new route-around CLI command that isolates the component without disrupting traffic.
•
Support has been added for automatically determining the maximum number of hops (depth) that the Subnet Manager has to search when configuring the InfiniBand fabric. This feature adds a new value 0 to the max-hops CLI configure command, which will cause the Subnet Manager to optimize IB paths for shortest distance.
•
A problem has been fixed where the CLI show neighbor command could show incorrect information.
•
A problem has been fixed where the Subnet Manager did not always set the Attribute Offset in GetTable Response IB protocol messages.
Caveats
This section describes temporary limitations of this release. These restrictions will be resolved in a future release of this product.
•
HSM is not supported running on OFED ppc64.
•
Running HSM on OFED 1.3 will produce the following benign syslog messages:
user_mad: process ib_sm did not enable P_Key index support.user_mad: Documentation/infiniband/user_mad.txt has info on the new ABI.•
