Very Computer

The large $TELCO I work for is starting to look into Linux; specifically
the RedHat distribution running on Itanium.  Two of our (many)
requirements are the creation (and regular updating) of an alternate boot
disk (currently ini Solaris we have a script that ufsdumps and writes a
bootblk to an alt device, in case the boot disk goes bad).  We are also
interested in connecting to an EMC SAN.  I would appreciate any feedback.
 Thank you
