The disc box(3 disks inside) is connected with a SCSI controller to the
computer. Is it possible to make
an LSM+Raid 5 with the above disk configuration?? Iam new to LSM.What
commands
I have to execute in which order? I could not see anything regarding
this type of raid configuration in the mailing list.
Thanks in advance and with regards,
