scsi for Sun 711 multipack
Hello,
I have a sun multipack 711 (6 disk version) I want to add disk and wondered which scsi disk and scsi interface would be appropriate. According to my research the 711 is ultra scsi.
Looking on ebay its difficult to ascertain which type of scsi interface would be best. I simply want to fill the box with fastest scsi possible for a home network project.
I am concerned about compatibility issues, ie is ultra320 compatible are newer scsi drives going to work.
Any help appreciated.
PS will be connected to sun blade 150 and a sun ultra 10

scsi-spin
scsi-spin(8) System Manager's Manual scsi-spin(8)
NAME
scsi-spin - spin up and down a SCSI device
SYNOPSIS
scsi-spin [-options...] [device]
DESCRIPTION
scsi-spin let the user to manually spin up and down a SCSI device.
This command is particularly useful if you've got noisy (or hot) drives in a machine that you rarely need to access. This is not the same
as the kernel patch that's floating around that will automatically spin down the drive after some time. scsi-spin is completely manual,
and spinning down a drive that's in use, especially the one containing the scsi-spin binary, is probably a really bad idea.
To avoid running in trouble with such cases, scsi-spin verifies that the device to work on is not currently in use by scanning the mounted
file system description file for a partition living on it and issue an error if this the case.
OPTIONS
-u, --up
spin up device.
-d, --down
spin down device.
-e, --loej
load or eject medium from drive (use along with -u or -d )
-w, --wait=[n]
wait up to n seconds for the spin up/down command to complete. Default is to return immediately after the command was sent to the
device. Either repeat -w n times or set n to define the time to wait before to report a timeout.
-l, --lock
prevent removal of medium from device.
-L, --unlock
allow removal of medium from device.
-I, --oldioctl
use legacy ioctl interface instead of SG_IO to dialog with device (could not be supported on all platforms). -e and -w are not
allowed with this option.
-v, --verbose=[n]
verbose mode. Either repeat -v or set n accordingly to increase verbosity. 1 is verbose, 2 is debug (dump SCSI commands and Sense
buffer).
-f, --force
force spinning up/down the device even if it is in use.
-n, --noact
do nothing but check if the device is in use.
-p, --proc
use /proc/mounts instead of /etc/mtab to determine if the device is in use or not.
device the device is any name in the filesystem which points to a SCSI block device (sd, scd) or generic SCSI device (sg). See section
below.
SCSI devices naming convention
Old kernel naming convention
It is typically /dev/sd[a-z] , /dev/scd[0-9]* or /dev/sg[0-9]*.
scsidev naming convention
It is typically /dev/scsi/s[rdg]h[0-9]*-e????c?i?l? or /dev/scsi/<aliasname>.
devfs naming convention
It is typically /dev/scsi/host[0-9]/bus[0-9]/target[0-9]/lun[0-9]/disc (same for cd and generic devices) or short name
/dev/sd/c[0-9]b[0-9]t[0-9]u[0-9] when devfsd "new compatibility entries" naming scheme is enabled.
