发现HACMP5.4.0.1的一个BUG

myguangzhou

记得之前在曾在一次项目实施过程中使用CSPOC来扩展FS的时候失败，具体错误信息忘记了；现在想起来这或许是HACMP5.4.0.1的一个BUG，当使用CSPOC在线向共享VG中添加FS和扩展FS时会导致该VG瞬间无法访问，并把资源组切换至另一节点。
解决办法有2：
1.扩共享VG\LV\FS时使用传统方式，即单节点完成后，进行IMPORT/EXPORT、同步
2.安装相关FIX：IY90392

=================================================================================
APAR status

Closed as program error.

Error description

The customer changed a filesystem size through CSPOC and
that failed, but it also resulted in moving the resource
group to the other node.

Local fix

Problem summary

****************************************************************
* USERS AFFECTED:
* Users of HACMP for AIX R540 performing C-SPOC operations with
* the cluster.es.cspoc.cmds and cluster.es.cspoc.rte filesets
* below the level of 5.4.0.2.
****************************************************************
* PROBLEM DESCRIPTION:
* C-SPOC operations on shared volume groups can result in the
* volume group becoming inaccessible.

Problem conclusion

Correct code added in 551404 to update timestamp to do so
without setting or leaving a reserve on the volume group
