DEC's restriction of 12 character labels for disk packs is very restrictive in a cluster environment where a consistent naming scheme is essential - more for the benefit of system users than for the general user who should be protected from physical device names and labels by using logical names. For those who are interested, the scheme I've used is as follows. The volume label is defined to be <nodename>$<idlabel>_<relvolnumber> chars 2-6 1 3-7 1 1 As the node name can be up to six characters, very little is left for unique identification of a volume. For the <idlabel>, I use values like SY01 ( system disk ) US01 ( user disk ) _<relvolnumber> is used to identify volumes in disk volume sets. Our node names are short ( max five characters ) and so the scheme 5 1 4 1 1 works well enough. John
