following ways. To improve system reliability it is recommended to duplicating (mirroring) the system disk.
A) Mount a Hard Disk Drive in a disk bay inside the server.
B) Ultra 320 SCSI cards, expansion file units together with external HDDs can also be used as system disks.
C) When using SAN Boot, fibre channel cards, RAID devices and system disks must be prepared. Use a disk in a
RAID device as the system disk. When installing the OS on the RAID device, you need to prepare another
installation server, or use one partition as an installation server using method A) above.
D) LAN Boot from other SPARC Enterprise Server is also possible.
