#
|
|
# xCAT plugin package to handle various commands that work with the
|
|
# xCAT tables
|
|
#
|
|
# Supported commands:
|
|
# nodeadd
|
|
# nodels
|
|
# nodech
|
|
# tabdump
|
|
# tabrestore
|
|
# noderm
|
|
# To be implemented:
|
|
# gettab
|
|
# chtab
|
|
# tabls
|
|
# getnodecfg (?? this doesn't seem much different from gettab)
|
|
# nr
|
|
# These were xCAT 1.2 commands. Are they still useful in xCAT 1.3?
|
|
# addattr
|
|
# delattr
|
|
# chtype
|
|
