How do I format an SGI filesystem?

Boot into the command monitor
Know the SCSI ID of whatever device you're booting from. Replace ID in the commands below with this number.
From a local CDROM, type: boot -f dksc(0,ID,8)sashARCS dksc(0,ID,7)stand/fx.ARCS --x
From an existing file system type: boot -f stand/fx --x
Select the [f]ormat option to format the drive. Sometimes this option isn't present, so use [a]uto instead. Usually, it's best to accept the default options. Select a block size of 4096 if you're not sure what to use.
Before formatting, I'd recommend entering the [exer]cise option, and selecting the [r]andom option. It tends to catch some i/o errors that the sequential and butterfly disk scans don't when fx formats a drive.
