Solaris 7 3/99 Release Notes Supplement for Sun Hardware

Dynamic Reconfiguration of Sun Enterprise 3x00, 4x00, 5x00, and 6x00 Servers

These release notes provide the latest information on Dynamic Reconfiguration (DR) functionality for Sun(TM) Enterprise 3x00/4x00/5x00/6x00 Servers running Solaris 7 3/99. For complete information on Sun Enterprise Server Dynamic Reconfiguration, please refer to Dynamic Reconfiguration User's Guide For Sun Enterprise 3x00/4x00/5x00/6x00 Systems.

For Solaris 7 3/99 software on Sun Enterprise 3x00/4x00/5x00/6x00 Servers, DR functionality is limited to I/O boards and does not include CPU/Memory boards.

Supported Hardware

Before proceeding, ensure the system has Dynamic Reconfiguration capabilities. If you see the following message on your console or in your console logs, the hardware is of an older design and not suitable for Dynamic Reconfiguration:

Hot Plug not supported in this system

Supported I/O boards are listed in the "Solaris 7" section on the web site

http://sunsolve2.sun.com/sunsolve/Enterprise-dr/

The supported hardware includes type 1 and 4 Sun Enterprise I/O boards.

Firmware Issues for Dynamic Reconfiguration

FC-AL Disk Arrays or Internal Drives

For Sun StorEdge(TM) A5000 disk arrays or for internal FC-AL disks in the Sun Enterprise 3500, the firmware version must be at least ST19171FC 0413. For more information, refer to the "Solaris 7" section at the DR web site:

PROM Updates for CPU and I/O Boards

To perform Dynamic Reconfiguration operations your machine may require one or more firmware updates. If an update is needed, the following message will appear during boot:

Firmware does not support Dynamic Reconfiguration

Your machine must be running at least CPU PROM version 3.2.16. If you updated your firmware from the Solaris 7 3/99 CD for 64-bit operation, you already have version 3.2.16 installed.

To see your current PROM revision, enter .version and banner at the ok prompt. Your display may be similar to the following:

Software Issues for Dynamic Reconfiguration

The pln_enable_detach_suspend and soc_enable_detach_suspend variables must be set in the /etc/system file. As root, edit the file and add the following lines:
```
set pln:pln_enable_detach_suspend=1
set soc:soc_enable_detach_suspend=1
```
On a large system, the cfgadm -x quiesce-test command may run as much as a minute or so. During this time no messages are displayed if cfgadm does not find incompatible drivers. This is normal behavior.
The system cannot use boards that are listed in the disabled-board-list. To remove all boards from the disabled board list, set the disabled-board-list variable to a null set by entering the system command:
```
# eeprom disabled-board-list=
```
If you are at the OpenBoot prompt, use this OBP command instead:
```
OK set-default disabled-board-list 
```
If it is necessary to unload detach-unsafe drivers, use the modinfo(1M) line command to find the module IDs of the drivers. You can then use the module IDs in the modunload(1M) command to unload detach-unsafe drivers.

Bug List on the Internet

For the current list of DR software bugs, refer to the "Solaris 7" section at this web site:

http://sunsolve2.sun.com/sunsolve/Enterprise-dr/

Cannot unconfigure board in slot 15; operation fails (4101093)

On Sun Enterprise 6000 and 6500 systems, the unconfigure operation fails for an I/O board in slot 15.

Cannot remove central I/O board (4112730)

The "central" I/O board cannot be removed under Dynamic Reconfiguration. On Sun Enterprise x000 and x500 systems the lowest-numbered I/O board is considered a key resource and cannot be removed.

PCI I/O board experiences Privileged Timeout Error during Connect (4122455)

The PCI I/O board (type 3 I/O board) experiences Privileged Timeout Error during connect. The PCI I/O board is therefore not supported at this time.
