SDD常用指令
addpaths
You can use the addpaths command to dynamically add more paths to SDD
devices while they are in the Available state. In addition, this command allows you
to add paths to vpath devices (which are then opened) belonging to active volume
groups.
hd2vp and vp2hd
SDD provides two conversion scripts, hd2vp and vp2hd. The hd2vp script converts
a volume group from ESS hdisks into SDD vpaths, and the vp2hd script converts a
volume group from SDD vpaths into ESS hdisks. Use the vp2hd program when you
want to configure your applications back to original ESS hdisks, or when you want
to remove the SDD from your AIX host system.
Note: You must convert all your applications and volume groups to the original
ESS hdisk device special files before removing SDD.
dpovgfix
You can use the dpovgfix script tool to recover mixed volume groups.
lsvpcfg
You can use the lsvpcfg script tool to display the configuration status of SDD
devices. This displays the configuration status for all SDD devices.
mkvg4vp
You can use the mkvg4vp command to create a SDD volume group.
extendvg4vp
You can use the extendvg4vp command to extend an existing SDD volume group.
