Boot Support and Limitations of Storage Adapters for the Model 170

The following adapters support external boot capabilities for the Model 170:

•PCI Universal Differential Ultra SCSI Adapter (# 6204)

•PCI Dual Channel Ultra2 SCSI Adapter (# 6205)

•PCI Single-Ended Ultra SCSI Adapter (# 6206)

•Advanced SerialRAID Plus Adapter (# 6230)1

1SSA boot is possible from an Advanced SerialRAID Plus Adapter (# 6230), provided a non-RAID SSA disk is included as part of the configuration. Other disks associated with the adapter can be RAID but at least one disk must be a non-RAID SSA disk. The non-RAID SSA disk can be located under the covers of a processor unit or in an external SSA storage unit. If your system is running with AIX 4.3.3 or later software, native boot capability is supported.

For factory system orders with AIX preload requested, an internal SCSI disk drive will be preloaded as the native boot disk even if internal SSA disk drive(s) are present.
