Appendix D Sun StorEdge T3 Array System Commands D-3
D.2 FRU Identifiers
Many commands use a FRU identifier to refer to a particular FRU in a array. This
identifier contains a unit constant (
u
), the unit number (encid), the FRU constant
(
ctr
for controller card,
pcu
for power and cooling unit,
l
for interconnect card,
d
for disk drive) and the FRU number (n).
TABLE D-2
lists the possible FRU variables as
they appear in this appendix
