Existing disk is c1t0d0, now attach new disk, then check with “cfgadm -al” command:

root@solaris10 # cfgadm -al
Ap_Id                          Type         Receptacle   Occupant     Condition
c0                             scsi-bus     connected    configured   unknown
c0::dsk/c0t0d0                 CD-ROM       connected    configured   unknown

c1::dsk/c1t0d0                 disk         connected    configured   unknown
c1::dsk/c1t1d0                 disk         connected    unconfigured   unknown
c1::sg/c0t0l0                  unknown      connected    configured   unknown
c1::sg/c0t1l0                  unknown      connected    configured   unknown
c2                             scsi-bus     connected    configured   unknown
c2::rmt/0                      tape         connected    configured   unknown
c2::sg/c0t5l0                  unknown      connected    configured   unknown
c3                             fc           connected    unconfigured unknown
c4                             fc           connected    unconfigured unknown
usb0/1                         unknown      empty        unconfigured ok
usb0/2                         unknown      empty        unconfigured ok
usb0/3                         unknown      empty        unconfigured ok

My new disk is C1t1d0 and the status is “unconfigured”.

Now, run “cfgadm -c configure”

# cfgadm -c configure c1::dsk/c1t1d0

{run cfgadm -al to check the status again:

# cfgadm -al

{run “format”, then you will see the new disk..
