I am new to this big arrays. FreeBSD 5.2.1 doesnt see all the 2.2TB.
So when I do
# dmesg |grep da0
GEOM: create disk da0 dp=0xc832fc50
da0 at twa0 bus 0 target 0 lun 0
da0: <3ware Logical Disk 00 1.00> Fixed Direct Access SCSI-0 device
da0: 100.000MB/s transfers
da0: 2384080MB (4882595840 512 byte sectors: 255H 63S/T 303927C)
#
and doing
# fdisk da0
******* Working on device /dev/da0 *******
parameters extracted from in-core disklabel are:
cylinders=303927 heads=255 sectors/track=63 (16065 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=303927 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 63, size 587625507 (286926 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 1023/ head 254/ sector 63
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
#
and it comes out.
How should I proceed.
Thanks
