悲惨,春节后开机当天,8300的HMC硬盘坏;
导致DS8300无法开机;
后重新安装HMC(3张盘)后，做restore critical data;
恢复完成,DS8300开机正常.并做硬件的verify都PASSED;
做cdapreverify发现检查HMC的machine type为空,和之前的x3550 7879..不一致;
开始认为无影响，因为对应的系统都正常。
但后来发现一个问题 PPRC切换异常.
原因是连不进dsm界面.
后经过种种检查更改,IBM二线操作，后正常。
-----
整个过程中发现的问题:
1 HMC的硬盘都是一个?之前本以为都是2个做RAID1的，但出问题后，经过检查，发现我这边DS8000的HMC都是一个硬盘，看来被忽悠了!!
不知道能否再增加一个，有朋友有此经验吗，请不吝赐教.感谢。
2PPRC受制于HMC,一台HMC的话，感觉还是有点弱.不知道是否其他方法。
若增加一个HMC的话，PPRC还是要查HMC的地址，若此HMC坏的话，还是需要更改PROFILE文件.感觉还是有问题，不知道是否有什么热备的方法.
此问题纯讨论.

Storage-Hardware Management Console
The S-HMC is used to perform configuration, management, and maintenance activities on the DS8000. It can be ordered to be located either physically inside the base frame or externally for mounting in a customer-supplied rack.
If the S-HMC is not operational then it is not possible to perform maintenance, power the DS8000 up or down, or perform Copy Services tasks such as the establishment of FlashCopies. It is thus recommended to order two management consoles to act as a redundant pair.
