SAN connection - configuring fibre attached hard drive

I knew I was missing something 
.
The disk I need to newfs is named c4t50060E800589B220d0 but when I go ls /dev/dsk/ I see c4t50060E800589B220d0sX where 0<=X<=7. I remember reading something about the naming convention and I am sure that the number after the 's' means something but I have no idea which one to choose for newfs...
Also, I would like to replace an existing filesystem with the new one and I would like to have all current data moved as well. What's the easiest way to do it? I'd rather not move everything to external storage, remove old filesystem, create a new one and move the data over...
EDIT: I figured it out, I newfsed the second slice and mounted it with a temp name, I will move the data over, delete the old filesystem and rename the temp filesystem. Thanks bluescreen for pointing me in the right direction.

gshsec
GSHSEC(8) BSD System Manager's Manual GSHSEC(8) NAME
gshsec -- control utility for shared secret devices SYNOPSIS
gshsec label [-hv] name prov prov ... gshsec stop [-fv] name ... gshsec clear [-v] prov ... gshsec dump prov ... gshsec list gshsec status gshsec load gshsec unload DESCRIPTION
The gshsec utility is used for setting up a device which contains a shared secret. The secret is shared between the given providers. To collect the secret, all providers are needed. If one of the components is missing, there is no way to get any useful data from the rest of them. The first argument to gshsec indicates an action to be performed: label Set up a shared secret device from the given components with the specified name. Metadata are stored in the last sector of every component. stop Turn off an existing shared secret device by its name. This command does not touch on-disk metadata! clear Clear metadata on the given providers. dump Dump metadata stored on the given providers. list See geom(8). status See geom(8). load See geom(8). unload See geom(8). Additional options: -f Force the removal of the specified shared secret device. -h Hardcode providers' names in metadata. -v Be more verbose. EXIT STATUS
Exit status is 0 on success, and 1 if the command fails. EXAMPLES
The following example shows how to create a shared secret device. The secret will be split between a slice on a local disk and a USB Pen drive. gshsec label -v secret /dev/ada0s1 /dev/da0 newfs /dev/shsec/secret From now on, when the USB Pen drive is inserted, it will be automatically detected and connected, making the secret available via the /dev/shsec/secret device. SEE ALSO
geom(4), gbde(8), geom(8), newfs(8) HISTORY
The gshsec utility appeared in FreeBSD 5.4. AUTHORS
