Hello,&nbsp;I tried to reply your email last nigh but the website was down.&nbsp; Anyway, please see my answers in line starting with "&lt;&lt;&lt;"Regards,Frank=========================================================Hi Frank,I check the disk group not to shared, only thing to do I use import and deport&nbsp; diskgroup, only one host can access the san disk.&nbsp; I am not sure if there is missing the patch on the vcs&nbsp;&nbsp;&lt;&lt;&lt; Since one node is not able to access the san disks, the disk group can only be imported on one host in this 2-node configuration.&nbsp; What you need to do is to make sure that OS of each node can access the shared disks needed for the dg.&nbsp; The output of the command below can be used to know if the disks of the dg can be accessed by each node#vxdisk -o alldgs list | grep debdg&lt;&lt;&lt; the issue is not likely a VCS patch related one.root@devuardbs01 # egrep -i "cvm|cfs" /etc/VRTSvcs/conf/config/main* | head -10&lt;&lt;&lt; so the dg was never configued as a cvm shared dgroot@devuardbs01 # hastatus -sum-- SYSTEM STATE-- System State FrozenA devuardbs01 RUNNING 0A devuardbs02 FAULTED 0-- GROUP STATE-- Group System Probed AutoDisabled StateB Oracle_MultiNIC devuardbs01 Y N ONLINEB Oracle_dev_SG devuardbs01 Y N OFFLINE|FAULTEDB Oracle_sit_SG devuardbs01 Y N OFFLINE|FAULTED-- RESOURCES FAILED-- Group Type Resource SystemC Oracle_dev_SG DiskGroup Oracle_devdg_Diskgroup devuardbs01C Oracle_dev_SG Oracle Oracle_dev devuardbs01C Oracle_sit_SG DiskGroup Oracle_sitdg_Diskgroup devuardbs01&nbsp;&lt;&lt;&lt; the output above shows that&nbsp; 1. node *02 was faulted2. service group Oracle_dev_SG was failed on node *01&nbsp; (check /var/VRTSvcs/log/engine_A.og and DiskGroup_A.log to know the cause of the failureRecommendations:1. check SAN/storage and ensure both nodes can axxess the shared storage2. review engine_A.log and DiskGroup_A.log so to determine the cause of the servi ce group online and DiskGroup resource failed issue3. reboot cluster (meaning reboot botrh nodes at the same time)Regards,Frank

in order top create or import a CVM diskgroup, vxvm needs to be in cluster mode.

run the command below on each node to see if all node can access the same shared storage

1. vxdisk -o alldgs list

2. vxclustadm -m vcs -t gab startnode

3. gabconfig -a

4. uname -a

5. haclus -display | grep -i vers

this lomd of problem is most often related to shafred storgae ex. ne node lost connectivity to some or all the shared storages.

If you post the above commands output, I shall be able to know the issue and assist you further.

Regards,

Frank
