Detecting Second disk

Hello all,

first of all, I apologise if I may ask stupid or obvious questions, but I'm new to UNIX and I think I need a little bit of help before I start gearing up Smilie

Anyway, I have installed a Solaris 8 on a Sun machine, and it has 2 physical disks in it. However, it seems that it is only recognizing one disk, that is, the disk that I have the Solaris installed on. I have checked from the vfstab file, and df command. All show c0d0t0s1 to s7 .

Is there a way how to make the UNIX system see the second disk?

Thanks and regards,
dragunu

/etc/vfstab will only show you filesystems that are mounted when the system boots, and df will only indicate filesystems that are currently mounted.

Please post the output of
Code:
format < /dev/null
uname -i

thanks for the useful reply zaz.
so format < /dev/null should lookout and possibly format unrecognized hardware on the machine?

I'm not a sun guru, but i'd first make sure the undentified disk's connection is 'good' then attempt to reconfigure the system like this
Code:
touch /.reconfigure; shutdown -g 0 -y -i6

And of course using command in OBP might be a good idea as well (show-disks, etc...)

Code:
touch /.reconfigure

should be
Code:
touch /reconfigure

Anyhoo, you should be able to get away with
Code:
devfsadm

without taking the system down.

thanks for the replies.

now when I am issuing the "format" command, i am getting the following error:

Code:
prompt scsi:       Error for Command: load/start/stop         Error Level: Retryable
prompt scsi:          Requested Block: 0                         Error Block: 0
prompt scsi:         Vendor: IBM                                Serial Number:             
prompt scsi:         Sense Key: Not Ready
prompt scsi:         ASC: 0x4 (LUN not ready), ASCQ: 0x0, FRU: 0x0
prompt scsi:  WARNING: /pci@1c,600000/scsi@2/sd@1,0 (sd1):

actually, it prompts up every time i start the machine.

hi !
u can c the 2nd hard disk with format command as root user.
it will show the no at the begining of each disk like c0t0d0
enter the no at format> prompt
after that type partition at format prompt
after that type print at partition prompt.
u can able to c the no of slices created on 2nd hard disk if u given the 2nd hard disk no at format prompt.
if no slice has been created u have to create slice here by entering slice no at partition prompt.
after that quit from partition prompt and then from format prompt.
now create the file system for that newly created slices
using newfs /dev/rdsk/c0t1d0s0(this is example)
now mount that filesystem using mount -f ufs /dev/dsk/c0txdxsx /newdir
where xin c0txdxsx is any numeric and /newdir is directory to mount that file system.
now u can c the file system with df -k command
with different target id like c0t1d0s0 which is different disk from the OS installed disk.
to make it permanent add this entry to /etc/vfstab.
