Problem
The command "vxdisk -eo alldgs list" showed the disk group in a deported status:
disk_2 auto:cdsdisk - (huievidg) online shared sdb -
disk_3 auto:cdsdisk - (huievidg) online shared sdc -
When an attempt to import the diskgroup is made, the error below is encountered.
Error
# vxdg -sC import huievidg
VxVM vxdg ERROR V-5-1-10978 Disk group huievidg: import failed:
Cannot find disk on slave nodeEnvironment
This can happen in any version of CVM, CFS, RAC in any supported Unix operating system.
Cause
This error is caused by all LUNs to the diskgroup not being visible to all nodes of the cluster as it is on the master node.
disk_2 auto:cdsdisk - (huievidg) online shared sdb -
disk_3 auto:cdsdisk - (huievidg) online shared sdc -
In CVM environment, the shared disk group could not be imported until all nodes could access the disk group physically.
Solution
run "hastatus -sum", there were six nodes in the cluster, then log on the other two nodes, there was one node which could not access the disks in the disk group.
Check with customer, customer re-connect the cables between server and storage array. then do the following commands:
#vxdisk scandisks
After that, the nodes could access the disks in the disk group
#vxdg -s import huievidg
The command did work. the disk group could be imported well.
