clssnmvDiskCheck: Aborting, 0 of 1 configured voting disks available, need 1

该BUG 13869978的特点是 当仅有一个votedisk时才会触发， 当使用ASM DISKGROUP存放votedisk时：

external redundancy  => 1份votedisk

normal   redundancy  => 3份

High     redundancy  => 5份

当使用external redundancy 时由于只有1份votedisk 所以可能触发该BUG

该bug 目前在11.2.0.3.3 +AIX上有补丁可以打

建议：

考虑使用 normal redundancy  的diskgroup存放votedisk ，或者 应用补丁13869978

Description

When we have a single voting file CSSD report the file offline, but thre is no IO error or hung condition
previous to taking the voting file offline:

[    CSSD][29](:CSSNM00018:)clssnmvDiskCheck: Aborting, 0 of 1 configured voting disks available, need 1

Rediscovery Notes:

If there is no IO error or IO hung that caused to set the voting file offline, then we may be getting this bug.

Use more than 1 voting file.
