ssa卡报42524错误！如何解决？急！！！

大开

查了服务手册，是这样描叙的
If a Fast-Write Cache Option Card fails, or is removed from the adapter, the affected
devices are all those that contain unsynchronized data when the cache card fails, or is
removed. To list these devices, type:
ssaraid -l ssaX -Iz -a state=no_cache
where X is the adapter number. Use the recovery procedure that is described for SRN
42520. You must recover all the devices that are listed.

Fast-Write Cache Option Card (100%)
(“Removing the Fast-Write Cache Option
Card of an SSA RAID Adapter” on
page 10-10 using system ).
Description: A fast-write disk drive (or drives) that does not contain
synchronized data has been detected. The Fast-Write Cache
Option Card, however, cannot be detected. The disk drive (or
drives) is offline.

Action:
? If the Fast-Write Cache Option Card has been removed,
replace it, and test the 7133.
? If the Fast-Write Cache Option card has failed:
1. Ask the customer to disable the Fast-Write option for:
– Each device for which the Fast-Write option is offline
– All other devices that are connected to the failing
adapter, and have the Fast-Write option enabled
For instructions on how to disable the Fast-Write option,
see “Dealing with Fast-Write Problems” on page 5-7.
2. Exchange the Fast-Write Cache Option Card for a new
one.
3. Ask the customer to re-enable the Fast-Write option for
the devices that are attached to the new Fast-Write
Cache Option Card.

我仔细看了相关资料，是不是应该这样做？
首先在逻辑磁盘上强制关闭cache，然后再打开

但现在环境是hacmp，而且该ssa卡连接的7133，上面共两个raid5，其中出现no_cache的raid5被另一台机器使用并且状态正常，但在本机显示no_cache;另一台raid5被本机使用(不是共享资源），且显示正常。

在这种得情况下应该怎样处理！

那建议在安全非工作时间在两台机器上分别diag.

获取详细确切的错误信息再来分析判断。
