M series servers can be configured into domains to have a better utilization of the server resources. There are 2 types of domains that can be created.
1. Static domain – Add and remove boards in an inactive domain
2. Dynamic domain – Add and remove boards in an active domain using solaris 10 DR (dynamic reconfiguration) operation.
We will be creating a static domain in this example. Before start creating the domain let us see the basic terminologies and their meanings.
| Terminology | Meaning |
|---|---|
| PSB | Physical system board. Consists of CPU, memory and I/O |
| XSB | eXtended system board. PSB can be configured as uni-board (00-0) with all components assigned to it or quad board (00-0, 00-1, 00-2, 00-3) with components assigned individually to these XSBs. The xx-y number specifies xx as PSB and y as number of partitions of PSB. |
| LSB | Logical system board. XSBs must be assigned to LSBs to create domain (16 LSBs per domain) |
| DID | Domain ID |
| CPUM | CPU module |
| MEMB | Memory board |
Supported number of domains
M4000/M5000 – supports as 4 domains (0-3)
M8000 – Supports 16 domains(0-15)
M9000 – Supports 24 domains(0-23)
Static Domain configuration example : M4000
M4000 server consists of :
1 PSB containing :
1 I/O unit (IOU 0) containing:
PCI-X slot : 1
PCI-E slots : 4
I/O devices : 2 disk, DVD, 2 GbE ports
2 CPU modules : CPUM0 and CPUM1 (containing 2 CPUs each)
4 Memory boards : MEB0, MEB1, MEB1, MEB3 (containing 8 DIMMS each)
Now we would create 2 domains:
domain 0 with XSB 00-0 and 00-2 Domain 1 with XSB 00-1 and 00-3
| XSB | CPU | Memory | I/O |
|---|---|---|---|
| XSB 00-0 | CPUM#0-CHIP#0 | MEMB#0 | Disks 0 & 1, DVD/DAT, GbE, IOU#0-PCI#0, IOU#0-PCI#1, IOU#0-PCI#2 |
| XSB 00-1 | CPUM#0-CHIP#1 | MEMB#1 | IOU#0-PCI#3, IOU#0-PCI#4 |
| XSB 00-2 | CPUM#1-CHIP#0 | MEMB#2 | None |
| XSB 00-3 | CPUM#1-CHIP#1 | MEMB#3 | None |
1. Setting up Domain 0
Quad-XSB configuration
XSCF> setupfru -x 4 sb 0
XSCF> showfru -a sb 0 Device Location XSB Mode Memory Mirror Mode sb 00 Quad no
Set a domain component list (DCL). setdcl associates a XSB with a LSB. LSB can be recognized by OS in a domain. We are assigning XSBs 00-0 and 00-2 to LSB 0.
XSCF> setdcl -d 0 -a 0=00-0 XSCF> setdcl -d 0 -a 1=00-2
Now configure XSBs 00-0 and 00-2 into domain 0.
XSCF> addboard -c assign -d 0 00-0 00-2 XSB#00-0 will be assigned to DomainID 0. Continue?[y|n] :y XSB#00-2 will be assigned to DomainID 0. Continue?[y|n] :y
Check the assignments
XSCF> showdcl -v -d 0
DID LSB XSB Status No-Mem No-IO Float Cfg-policy
00 Powered Off FRU
00 00-0 False False False
01 00-2 False False False
...
2. Setting up Domain 1
Now similarly configure the domain 1 using XSBs 00-1 and 00-3.
XSCF> setdcl -d1 -a 0=00-1 XSCF> setdcl -d1 -a 1=00-3
XSCF> addboard -c assign -d 1 00-1 00-3 XSB#00-1 will be assigned to DomainID 1. Continue?[y|n] :y XSB#00-3 will be assigned to DomainID 1. Continue?[y|n] :y
XSCF> showdcl -v -d 1
DID LSB XSB Status No-Mem No-IO Float Cfg-policy
01 Powered Off FRU
00 00-1 False False False
01 00-3 False False False
...
