发现HACMP5.4.0.1的一个BUG

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

Error description
