Yup, you can -- the command is scsi_id from the udev packages. Note that you have to have sysfs (/sys) mounted and active for this to work.
Determine the Linux block device name (e.g. /dev/sdc), then replace /dev/ with /block/ and pass it to scsi_id:
/sbin/scsi_id -g -u -s /block/sdc360a....
It's what the dm-multipath software uses to determine which devices are the same LUN.

I was aware that I can get this kind of information from the Host Utilities but was wondering if there was a way to get the info without installing Host Utilities. I'd be mainly interested in Linux.
Thanks for the help.

There are tools in the NetApp Host Utilities that already do this very thing. It is recommended (and on some platforms it's mandatory) that you use this method to connect your systems to the NetApp SAN.
On unix systems, a popular command that I use is:
sanlun lun show -p
Unfortunately, I am not as verse on Windows systems, but I expect something similar (if not the same). Good luck.

Subject: lun serial question
I recently became aware of the lun serial command and am wondering if there is anyway for a client that has said lun or luns presented to them to "see" this lun serial string. I'm thinking this would be an ideal way (i.e. script) to find out which lun corresponds to which filesystem/mountpoint on servers with lots of luns.
Thanks,
