Adding a Hard Drive to Solaris 10 (Copas http://utahsysadmin.com/2008/02/07/adding-a-hard-drive-to-solaris-10)

Here’s how you would add a hard drive to Solaris 10, including the format, fdisk, partition, and then creation of the file system. Of course, you first need to actually add the hard drive physically to the machine, I’m not going to cover that – if you don’t know how to do that then the rest of the information isn’t going to help!
If you installed a drive through VMWare while the VM is running, you will need Solaris to recognize the new drive. In this case, run devfsadm, otherwise boot your system and Solaris should recognize the new drive.
First, here’s the original drives (c0t0d0 & c1t0d0):

# ls /dev/rdsk/*s0
/dev/rdsk/c0t0d0s0 /dev/rdsk/c1t0d0s0

Have Solaris check for new hardware:

# devfsadm

Now you can see there is a new disk on another bus (c1t1d0):

# ls /dev/rdsk/*s0
/dev/rdsk/c0t0d0s0 /dev/rdsk/c1t0d0s0 /dev/rdsk/c1t1d0s0

Next, we want to format the drive (which includes creating the partitions):

# format
Searching for disks…done
AVAILABLE DISK SELECTIONS:
0. c1t0d0
/pci@0,0/pci1000,30@10/sd@0,0
1. c1t1d0
/pci@0,0/pci1000,30@10/sd@1,0
Specify disk (enter its number):

Type “1″, the option for the new drive and hit “enter”. Depending on the type of disk it may be preformatted:

selecting c1t1d0
[disk formatted]

If your drive is not formatted, type format at the format prompt to low level format your hard drive. Next, we need to use fdisk to create the partitions, type “y” to create the default Solaris partition:

format> fdisk
No fdisk table exists. The default partition for the disk is:
a 100% “SOLARIS System” partition
Type “y” to accept the default partition, otherwise type “n” to edit the
partition table.
y

Next enter the partition menu, by typing partition:

format> partition

You can print out the current partitioning first if you like:

partition> print
Current partition table (original):
Total disk cylinders available: 1020 + 2 (reserved cylinders)
Part Tag Flag Cylinders Size Blocks
0 unassigned wm 0 0 (0/0/0) 0
1 unassigned wm 0 0 (0/0/0) 0
2 backup wu 0 – 1020 1.99GB (1021/0/0) 4182016
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0
8 boot wu 0 – 0 2.00MB (1/0/0) 4096
9 unassigned wm 0 0 (0/0/0) 0

In this case, I just want to create one large partition for some extra storage so I will allocate all I can to partition 0. Note that partition 2 is used to reference the entire drive and is not a usable partition. To modify a given partition, just enter the number of the partition at the partition prompt:

partition> 0
Part Tag Flag Cylinders Size Blocks
0 unassigned wm 0 0 (0/0/0) 0
Enter partition id tag[unassigned]:
Enter partition permission flags[wm]:
Enter new starting cyl[0]: 1
Enter partition size[0b, 0c, 1e, 0.00mb, 0.00gb]: 1019c

And now to print the partition table again you can see what has changed:

partition> print
Current partition table (unnamed):
Total disk cylinders available: 1020 + 2 (reserved cylinders)
Part Tag Flag Cylinders Size Blocks
0 unassigned wm 1 – 1019 1.99GB (1019/0/0) 4173824
1 unassigned wm 0 0 (0/0/0) 0
2 backup wu 0 – 1020 1.99GB (1021/0/0) 4182016
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0
8 boot wu 0 – 0 2.00MB (1/0/0) 4096
9 unassigned wm 0 0 (0/0/0) 0

Save your changes by writing the label to the disk:

partition> label
Ready to label disk, continue? y

Quit out of the partition prompt, and then the format prompt, which takes you back to the command prompt:

partition> quit
format> quit
#

Now we are ready to create a file system on this new partition (in this case UFS).

# newfs /dev/rdsk/c1t1d0s0
newfs: construct a new file system /dev/rdsk/c1t1d0s0: (y/n)? y
/dev/rdsk/c1t1d0s0: 4173824 sectors in 1019 cylinders of 128 tracks, 32 sectors
2038.0MB in 45 cyl groups (23 c/g, 46.00MB/g, 11264 i/g)
super-block backups (for fsck -F ufs -o b=#) at:
32, 94272, 188512, 282752, 376992, 471232, 565472, 659712, 753952, 848192,
3298432, 3392672, 3486912, 3581152, 3675392, 3769632, 3863872, 3958112,
4052352, 4146592

Make sure that the file system is clean:

# fsck /dev/rdsk/c1t1d0s0
** /dev/rdsk/c1t1d0s0
** Last Mounted on
** Phase 1 – Check Blocks and Sizes
** Phase 2 – Check Pathnames
** Phase 3a – Check Connectivity
** Phase 3b – Verify Shadows/ACLs
** Phase 4 – Check Reference Counts
** Phase 5 – Check Cylinder Groups
2 files, 9 used, 2020758 free (14 frags, 252593 blocks, 0.0% fragmentation)

Next, add the proper line to /etc/vfstab:

/dev/dsk/c1t1d0s0 /dev/rdsk/c1t1d0s0 /data ufs 2 yes -

And then mount the partition. In this case, I’m making a /data partition:

# mkdir /data
# mount /data
# df -h /data
Filesystem size used avail capacity Mounted on
/dev/dsk/c1t1d0s0 1.9G 2.0M 1.9G 1% /data
