如何启动域

此过程描述如何启动现有的绑定域。如果具有指定域名的域不存在或尚未绑定，此操作将会失败。

1. 确认 domain-name 域存在且已绑定。

   # ldm list domain-name

2. 标识 ldomTable 中的 domain-name。

   # snmpwalk -v1 -c public localhost SUN-LDOM-MIB::ldomTable
   SUN-LDOM-MIB::ldomName.1 = STRING: primary
   SUN-LDOM-MIB::ldomName.2 = STRING: LdomMibTest_1
   SUN-LDOM-MIB::ldomAdminState.1 = INTEGER: 0
   SUN-LDOM-MIB::ldomAdminState.2 = INTEGER: 0
   SUN-LDOM-MIB::ldomOperState.1 = INTEGER: active(1)
   SUN-LDOM-MIB::ldomOperState.2 = INTEGER: bound(6)
   SUN-LDOM-MIB::ldomNumVCpu.1 = INTEGER: 8
   SUN-LDOM-MIB::ldomNumVCpu.2 = INTEGER: 4
   SUN-LDOM-MIB::ldomMemSize.1 = INTEGER: 3360
   SUN-LDOM-MIB::ldomMemSize.2 = INTEGER: 256
   SUN-LDOM-MIB::ldomMemUnit.1 = INTEGER: megabytes(2)
   SUN-LDOM-MIB::ldomMemUnit.2 = INTEGER: megabytes(2)
   SUN-LDOM-MIB::ldomNumCrypto.1 = INTEGER: 1
   SUN-LDOM-MIB::ldomNumCrypto.2 = INTEGER: 0
   SUN-LDOM-MIB::ldomNumIOBus.1 = INTEGER: 2
   SUN-LDOM-MIB::ldomNumIOBus.2 = INTEGER: 0
   SUN-LDOM-MIB::ldomUUID.1 = STRING: 5f8817d4-5d2e-6f7d-c4af-91b5b34b5723
   SUN-LDOM-MIB::ldomUUID.2 = STRING: 11284146-87ca-4877-8d80-cd0f60d5ec26
   SUN-LDOM-MIB::ldomMacAddress.1 = STRING: 00:14:4f:46:47:d6
   SUN-LDOM-MIB::ldomMacAddress.2 = STRING: 00:14:4f:f8:d5:6c
   SUN-LDOM-MIB::ldomHostID.1 = STRING: 0x844647d6
   SUN-LDOM-MIB::ldomHostID.2 = STRING: 0x84f8d56c
   SUN-LDOM-MIB::ldomFailurePolicy.1 = STRING: ignore
   SUN-LDOM-MIB::ldomFailurePolicy.2 = STRING: ignore
   SUN-LDOM-MIB::ldomMaster.1 = STRING:
   SUN-LDOM-MIB::ldomMaster.2 = STRING:
   SUN-LDOM-MIB::ldomExtMapinSpace.1 = STRING: off
   SUN-LDOM-MIB::ldomExtMapinSpace.2 = STRING: off
   SUN-LDOM-MIB::ldomWholeCore.1 = INTEGER: 0
   SUN-LDOM-MIB::ldomWholeCore.2 = INTEGER: 0
   SUN-LDOM-MIB::ldomCpuArch.1 = STRING: native
   SUN-LDOM-MIB::ldomCpuArch.2 = STRING: native
   SUN-LDOM-MIB::ldomShutdownGroup.1 = INTEGER: 0
   SUN-LDOM-MIB::ldomShutdownGroup.2 = INTEGER: 15
   SUN-LDOM-MIB::ldomPerfCounters.1 = STRING: htstrand
   SUN-LDOM-MIB::ldomPerfCounters.2 = STRING: global,htstrand
   SUN-LDOM-MIB::ldomNumCMI.1 = INTEGER: 0
   SUN-LDOM-MIB::ldomNumCMI.2 = INTEGER: 0

3. 启动 domain-name 域。

   使用 snmpset 命令，可以通过将 ldomAdminState 属性的值设置为 1 来启动域。n 指定要启动的域。

   # snmpset -v version -c community-string hostname \
   SUN-LDOM-MIB::ldomTable.1.ldomAdminState.n = 1

4. 使用以下命令之一验证 domain-name 域是否处于活动状态：

   • # ldm list domain-name

   • # snmpget -v version -c community-string hostname SUN-LDOM-MIB::ldomOperState.n

此示例在将 ldomAdminState 属性设置为 1 之前，先验证 LdomMibTest_1 域是否存在且已绑定。最后，ldm list LdomMibTest_1 命令验证 LdomMibTest_1 域是否处于活动状态。

# ldm list LdomMibTest_1
# snmpset -v1 -c private localhost SUN-LDOM-MIB::ldomTable.1.ldomAdminState.2 = 1
# ldm list LdomMibTest_1

您还可以使用 snmpget 命令（而不是使用 ldm list 命令）检索 LdomMibTest_1 域的状态。

# snmpget -v1 -c public localhost SUN-LDOM-MIB::ldomOperState.2

请注意，如果在使用 snmpset 启动域时域处于非活动状态，则域将首先绑定然后再启动。
