E.2 Editing the sd.conf File
Edit the
/kernel/drv/sd.conf
file to add more targets and LUNs, up to 128
LUNs, which can be used in a single SANnet II 200 SCSI array. Then reboot the host.
You might want to allow a few extra LUNs for flexibility over the coming months, but
generally most administrators minimize the number of unused LUNs because each
LUN causes a seven-second delay when you reboot the host.
Note –
The maximum number of LUNs per target is 32.
Caution –
After you edit
sd.conf
, you must reboot the host to enable the new LUN
assignments.
