Dear Rj,

I am bit confused by the question. What u asking is increasing the size of harddisk. I don't think u can increase the size of the hard disk rather u can increase the size of a file system

What you can do, that u can add a separate silce to an existing file system to increase it's size.

Here are some steps to do the things.

Suppose u have /home mounted on /dev/rdsk/c0t0d0s7.. Here u can increase the size of /home. suppose u have another hard disk(c1t0d0) and u want to add the fihth slice (c1t0d0s5) to /home for increasing the size.

step 1 : create the metadevices by metadb command. If alrady configured then leave it.

STEP 2 :
# metainit -f d* 2 1 c0t0d0s7(i:e /home) 1 c1t0d1s5 (new slice)

STEP 3:
Edit the /etc/vfstab and input the below entry

/dev/dsk/c0t0d0s7 /dev/rdsk/c0t0d0s7 /export/home ufs 2 yes - <Old entry >

now give this new entry and omit the above entry

/dev/md/dsk/d* /dev/md/rdsk/d* /export/home ufs 2 yes -

STEP 4: then unmount /home and mount it back.

STEP 5 : this is the important command

# growfs -M /home /dev/md/rdsk/d*

now u can check df -h to find out whether the size is increased or not.

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
