Thanks a lot guys.
I installed the sun device detection tool and verified that the pci scsi adapter is not compatible.
I may need to read more about beginner's guide in solaris as I really dont know where to start.
-----Post Update-----
another follow up guys..
i removed the scsi card that i originally installed.. it turned out that the card is only compatible with sun os 32-bit and not 64-bit..
when i changed it to another scsi card, i was able to detect it thru cfgadm, it shows the scsi-bus, and it says connected but the status is unknown.
i use devfsadm to configure it but no luck as there is no /dev/rmt/0 directory or if i use " for foo in 0 1 2 3 4 5 6 and check the status using mt -f status,it says not found.
i tried to use /var/adm to verify the activity of scsi drive but says cannot execute.
sorry guys, im at lost now after sun is able to detect the scsi card and tape drive., i guess the question now is how to configure the scsi and tape drive so that i can start a backup..
thanks again..

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.
