distributed disk on a cluster

[kacou]

i install a new disk in a cluster. but i can not activate the DLVM on my system using SAM.
see the error message below
--------------
SAM was unable to establish a remote connection to the system medprod
due to a network failure or an RPC failure. Check the SAM log file using the Options menu or the /usr/sam/bin/samlog_viewer command for more details on the failure. You must resolve the problem before SAM
will be able to perform tasks on the remote system.

Hi Kacou,

Can you tell exactly how you want to distribute the disk. What servers are part of cluster. Is it a serviceguard cluster? How are you trying to distribute the disk?
Giving more details would help.

Regards,
Vihang.

I put two hard drives in each server. And with SAM the system asked to me if I want that this disk is seen by the other server of the cluster. I said OK. Then I received the error message above.
I also noted that the first disk are â DLVMâ whereas those which I installed are â lvmâ . thus there are not distributed.

Are you trying to add two internal disks to existing nodes running in SG cluster ?

Adding disk to a cluster will be different here.

[kacou]

I install two external news disks in the array (cluster).

help me please

[Deepak Kr]

Please confirm the array you are using here.

also tell, if you are able to see two disks after running ioscan or only one disk?

Once you can see disk(S) in ioscanand run insf -e -C disk

You must after extend the Volumegroup and the Logical Volume, adapting the Volume Configuration on the one cluster node.
Then you can do follow:
1.) create a new map file (updated)
vgexport -p -s -v -m vgxx.mymap /dev/vgxx
copie the created mapfile via ftp or RCP on the backup server.
2.) on other cluster nodes
vgexport /dev/vgxx
mkdir /dev/vgxx
mknod /dev/vgxx/group c 64 0x0n000
vgimport -s -v -m vgxx/mymap /dev/vgxx

Hope this will answer your query!!!
