Edit configuration cluster

[Eli Daniel]

Hi,
i have add new disk and vg in the produccion system (High Availability). The cluster is Serviceguard.
later adding and creating (disk, vg) have export vg to server Failover
the comannd used in the server primary
vgexport -m ./vgxx.map -p -s -v vgxx
vgchange -a n vgxx
copy file in the server failover

the command used in the server failover
vgimport -m ./vgxx.map.map -s -v vgxx.map
vgchange -a r vgxx
vgchange -a n vgxx

my question is in the case of the vg existing:

In the failover server have delete vg existing before the apply command (vgimport)??

if you are asking:
Must I delete the exisiting VG information on the second cluster node if I am making major changes to my shared VG?
The answer is yes. You need to do the vgexport/mkdir/mknod command chain before doing the vgimport

thanls melvin, in the case, the following command apply before to vgimport

vgexport -v vgxx

i don not understang comment to mknod

if vg in the server failover exist, the number mknod is equal in the server primary

[melvyn burnard]

you will need to create the relevant VG directory same as the Primary node, themn create the Group control file with mknod.
All detailed in the Managing Serviceguard manuals
