Any ideas on this??

Should be backquotes, not forward quotes. uname -i is a command that
will expand into part of the path.

Other question is that how do I find out which LUN is available to
system. I mean once the storage person assigns a server a LUN how do I
make use of that LUN, which command should I use to use that LUN. My
server is using Solstice DiskSuite 4.2.1.

Depends on your HBA and storage drivers. Sometimes you need to edit
some files and reboot. Sometimes you just run cfgadm and enable a
controller or storage.

Once the LUN is available for the system am I still limited to 7
partitions on that LUN?

If you use a SPARC SMI label, then yes there are a maximum of 8 slices
on it. Of course you can create more metadevices than you have slices
(via soft partitions), so since you say you're using DiskSuite, that
shouldn't be a big drawback.

Do I have to mirror all the LUNS?

You don't mirror LUNS with Disksuite, you mirror segments of them
(metadevices). And no, you don't have to use any mirrors if you don't
want to.

Once I have mirored my internal HDD would they automatically stay in
synch or do I have to do some commands to keep the drives synched?

All writes to the mirrored metadevice will be delivered to all
components, keeping them in sync. If you go behind its back and write
to one device directly, then synchronization is broken and DiskSuite
will not detect it.
