Unconfiguring and Reconfiguring

Devices

To support a degraded boot capability, the ALOM firmware provides the disablecomponent command, which enables you to unconfigure system devices manually. This command flags the specified device as disabled by creating an entry in the ASR database.

▼To Unconfigure a Device Manually

●At the sc> prompt, type:

sc> disablecomponent asr-key

The asr-keyis one of the device identifiers from TABLE 2-5

Note – The device identifiers are not case-sensitive. You can type them as uppercase or lowercase characters.

TABLE 2-5Device Identifiers and Devices

Device Identifiers	Devices

MB/CMPcpu-number/Pstrand-number	CPU strand (Number: 0-31)
MB/PCIEa	PCIe leaf A (/pci@780)
MB/PCIEb	PCIe leaf B (/pci@7c0)
MB/CMP0/CHchannel-number/Rrank-number/Ddimm-number	DIMMs

▼To Reconfigure a Device Manually

●At the sc> prompt, type:

sc> enablecomponent asr-key

where asr-keyis any device identifier from TABLE 2-5.
