SSP 3.5 Release Notes |
This chapter covers the following topics:
This section discusses general issues for SSP 3.5 software.
If you are currently using alternate pathing (AP) software on your Sun Enterprise 10000 domains with dynamic reconfiguration (DR), note that you must use multipathing software compatible with the type of DR model (either 2.0 or 3.0) running on those domains. For further information on DR models, see Changes to the SSP Software .
For multipathing on DR model 2.0 domains, run the Sun Enterprise Server Alternate Pathing software. For further AP information, refer to the Sun Enterprise Server Alternate Pathing User Guide.
For multipathing on DR model 3.0 domains, run Internet Protocol Multipathing (IPMP) software provided with the Solaris 8 or 9 operating environment--and the Sun StorEdge Traffic Manager software (formerly known as Multiplexed Input and Output (MPxIO) software). For details on IPMP software, refer to the IP Network Multipathing Administration Guide available in the Solaris 8 operating environment or the System Administration Guide: IP Services documentation available in the Solaris 9 operating environment.
For details on the Sun StorEdge Traffic Manager, refer to the Sun StorEdge Traffic Manager Software Installation and Configuration Guide available on the Sun Network Storage Solutions Web site ( http://www.sun.com/storage/san ).
The Sun Netra T1, a rackmounted thin server, can now be used as an SSP. For further information on the Netra T1, refer to the Netra t1 User and Administration Guide .
Support for 466 MHz processors.
Performance improvements that enable the SSP to function continuously under adverse conditions, such as when CPU and memory utilization is high.
These improvements use real-time processes and enable the SSP to retry operations without creating further excessive load on the SSP workstation or server.
OpenSSP refers to the capability to run lightweight, third-party applications--other than the SSP software and the Solaris operating environment--on an SSP workstation or server.
However, be sure that your SSP meets the resource requirements for running third-party applications along with the SSP software, as explained in Chapter 7 .
There are two different models for dynamic reconfiguration. The DR model number indicates the type of DR functionality running on a Sun Enterprise 10000 domain:
DR model 2.0 - Uses the dr_daemon to control DR operations on the domain. You can use Hostview, dr (1M) shell, or automated dynamic reconfiguration (ADR) commands on the SSP to perform DR operations.
DR model 2.0 is the default for domains running the Solaris 8 10/01 (Update 6) operating environment. If you want to run DR model 3.0 (explained later) on a domain, refer to the instructions for switching DR models in the Sun Enterprise Dynamic Reconfiguration User Guide .
DR model 3.0 - Uses the domain configuration server, dcs (1M) to control DR operations on the domain. You use the ADR commands on the SSP to perform DR operations. DR model 3.0 is consistent with DR functionality provided on other Sun server lines.
DR model 3.0 also interfaces with the Reconfiguration Coordination Manager (RCM) feature, which enables you to coordinate DR operations with other applications running on the domain, such as database, clustering, and volume management software. Such applications can register to receive notification of DR operations and coordinate their software activities with DR. For details on RCM, refer to the System Administration Guide: Basic Administration in the Solaris 9 System Administrator Collection.
Note - DR model 3.0 is available only in the Solaris 8 10/01 and 02/02 or Solaris 9 operating environment. DR model 3.0 also requires that SSP 3.5 software be running on the SSP. Only DR 3.0 runs in a domain running the Solaris 9 operating environment. For instructions on installing or upgrading to the Solaris 8 or 9 operating environment, see Chapter 8 and Chapter 9. |
For details on DR and how the DR models work, refer to the Sun Enterprise 10000 Dynamic Reconfiguration User Guide and the Sun Enterprise 10000 Dynamic Reconfiguration Reference Manual .
This section summarizes the changes to commands and behavior for DR and SSP 3.5:
TABLE 1-1 explains the command changes related to DR.
TABLE 1-2 describes the changes in SSP commands.
The following table describes where you can find additional DR information.
This section describes software bugs for SSP 3.5 software that you may notice or that can affect the software operation. Also check the Solaris Release Notes Supplement for Sun Hardware for your Solaris operating environment for additional release notes pertaining to the Sun Enterprise 10000.
Memory leaks related to the snmpd daemon can occur after multiple addboard (1M), deleteboard (1M), or moveboard (1M) operations.
Workaround: If SSP performance is affected by this memory leak, stop and start SSP daemons by doing the following:
As superuser on the main SSP, type:
Memory leaks related to the machine_server daemon can occur after multiple addboard (1M), deleteboard (1M), or moveboard (1M) operations.
Workaround: If SSP performance is affected by this memory leak, stop and start SSP daemons by doing the following:
As superuser on the main SSP, type:
This section describes software bugs for this version of DR software that you may notice or that can affect the software operation.
If a device fails to resume after a DR detach operation, the resume failure can prevent subsequent DR operations.
on a board that contains no memory, and the domains involved are running the Solaris 7 or Solaris 8 operating environment, the affected domains may crash or hang.
Workaround: Perform DR operations only on boards with memory.
A panic can occur under certain circumstances when the /dev/openprom interface accesses the PROM device tree after a DR disconnect. The openprom driver caches node information that can become invalid after a DR disconnect. As a result, OBP can be passed a bad node address.
Workaround: To minimize the possibility of encountering this situation, discontinue using applications, such as prtconf , that use the /dev/openprom interface during or immediately before or after a DR disconnect operation. Note that picld (1M) uses the /dev/openprom driver.
Domains running both DR 3.0 and Solaris 8 cause the showdevices (1M) command to display 0x0 as the base memory address.
Workaround: Obtain base memory address information by using the rcfgadm (1M) command.
