功能时需执行以下步骤：

1. 运行odmget -q name = xxxx CuDv命令获取硬盘类型信息。
2. 运行smit hacmp命令。
3. 在“HACMP for AIX”配置界面中选择目录“Extended Configuration”“Extended
   Resource Configuration”“HACMP Extended Resources Configuration”“Configure
   Custom Disk Methods”“Add Custom Disk Methods”。
4. 在如下打印页面中，将“1”中获取的硬盘类型信息输入“New Disk Type”后的字段内。

8. Method to break a reserve [/usr/sbin/ReserveBreak] +
   Break reserves in parallel
   false +
9. Method to make the disk available [MKDEV]
10. 按“Enter”键完成ReserveCheck和ReserveBreak功能配置。

lspv

lsattr –El hdiskX X为磁盘号

修改队列深度

chdev -l hdiskX -a queue_depth=32 –P 所有磁盘均需要修改

修改reserve_policy

chdev -a PR_key_value=1(主)

chdev -a PR_key_value=2(备)

chdev -a PR_key_value=2 -l hdiskX 所有磁盘均需要修改

chdev -a reserve_policy=PR_exclusive -l hdiskX 所有磁盘均需要修改

配置ReserveCheck 和ReserveBreak 功能
odmget -q name = xxxx CuDv和smit hacmp命令用于配置ReserveCheck和ReserveBreak
功能。配置了ReserveCheck和ReserveBreak功能后，当一个节点失效时，另一个节点
将自动调用ReserveCheck和ReserveBreak来接管失效节点的资源。
