When using US-IV+ System boards in a Sun Fire Midrange server with Repeater version 1 (V1) boards, only one active domain is allowed per partition. The System Controller firmware will enforce this requirement.

The impacted Repeater Boards are only the V1 version; V2 Repeater Boards do NOT require this restriction, and as such do NOT limit the configuration to only one domain per partition.

Note that the minimum supported firmware version with US-IV+ boards is 5.19.1.

Any US-IV+ board in a system with V1 repeaters will cause this restriction to be enforced on a per-partition basis.

(See below for a table of possible domain combinations.)

The following example shows the error encountered when attempting to bring up a domain with an US-IV+ board without properly configuring it, i.e., without first running "setupplatform -p usiv+ ".  Note that /N0/SB4 is the US-IV+ board.

   v4u-4800b-sc0:A> setkeyswitch on
   Powering boards on ...
   Aug 25 12:37:23 v4u-4800b-sc0 Domain-A.SC: ERROR: UltraSPARC IV+ CPUs
   detected in this domain. Domain is not set up to support UltraSPARC IV+.
   Please setkey off this domain, run setupplatform to support UltraSPARC IV+ CPUs in domain A.

   keyswitch is: standby
  
   v4u-4800b-sc0:A> setkeyswitch off

To verify this, type the following commands on the SC :

   v4u-4800b-sc0:SC> showplatform -p usiv+
UltraSPARC IV+ is not supported in domain A
UltraSPARC IV+ is not supported in domain C

There is a limitation in the AR ASIC specific to its use on the Sun Fire Mid-Range Level 2 Repeater Board Version 1. When multiple domains are configured in the same partition, the limitation could result in a domain interruption. Therefore, in order to avoid that possibility, only one domain per partition is allowed when US-IV+ boards are in a partition and Version 1 repeaters are in use. If US-IV+ boards exist only in one partition, the other partition may have two domains.

The firmware will enforce the appropriate restrictions per the tables below, so no specific user actions are required.

If the user needs to use US-IV+ *and* has two domains per partition, the system must be upgraded with V2 repeaters.

Configuration Examples when using V1 repeaters:

If US-IV+ Boards will *only* go into domain A, it is possible to have two domains in the second partition, C and D. Likewise, if US-IV+ Boards will *only* go into domain C, it is possible to have two domains in the first partition, A and B. Remember that using an US-IV+ board in either domain B or D is not allowed in any configuration.  See tables below.

Sun Fire 4800/E4900 

Sun Fire 6800/E6900

The "setupplatform -p usiv+" command needs to be run during installation of US-IV+ boards.  This command tells the SC which domains are intended to contain US-IV+ boards and allows US-IV+ boards to be used there.  This command can only be run when the domains in the partition have their keyswitches in the OFF position. "showplatform -p usiv+" displays whether the SC believes US-IV+ boards will be used in the specified domain.

Example:

   v4u-4800b-sc0:SC> showplatform -p usiv+
   UltraSPARC IV+ is not supported in domain A
   UltraSPARC IV+ is not supported in domain C
   v4u-4800b-sc0:SC> setupplatform -p usiv+
   UltraSPARC IV+ Configuration
   ----------------------------
   Is UltraSPARC IV+ going to be deployed in domain A? [false]: true
   Domain A keyswitch position is standby. The position must be off.
   Can not change this value when the above domains are powered on.
   v4u-4800b-sc0:SC> setkeyswitch -d A off
   Powering boards off ...
   v4u-4800b-sc0:SC> setupplatform -p usiv+
   UltraSPARC IV+ Configuration
   ----------------------------
   Is UltraSPARC IV+ going to be deployed in domain A? [false]: true
   Is UltraSPARC IV+ going to be deployed in domain C? [false]: false
   v4u-4800b-sc0:SC> showplatform -p usiv+
   UltraSPARC IV+ is supported in domain A
   UltraSPARC IV+ is not supported in domain C

Note:

When using US-IV+ and V1 repeater boards, you cannot use domains B and D, even by themselves. The System Controller firmware will enforce the domain restrictions. You cannot choose to run multiple domains in a partition "at your own risk". It is not allowed. If the MAC address/hostid are needed from domains B or D, use the MAC Address change procedure outlined in the Systems Platform Administration Manual included with the firmware.

Repeater Board V2 boards (501-7594) are NOT impacted by this issue.

To check if the system has Repeater Board V2 installed, run the showboards command, which identifies 501-7594 as Repeater Board V2. The V1 Repeater Boards are simply identified as Repeater Board (No V number at all).

If only Repeater Board V2 is installed, the system can support up to two domains per partition.

It should, however, be noted that there may be some performance implications when creating two domains per partition when using US-IV+.
