请教COMPAQ RA7000磁盘阵列中坏硬盘的处理问题

mykings

我有点晕，如果你不试验，理论上探讨是没有结果的。

总是可能……可能……再可能了，呵呵。

这个是没有问题的，坏掉的盘是9G的，spareset一个是18G，坏了之后又做了一个9G的spareset，但是都没有自动替换上。
我在磁盘柜中运行一下SET FAILEDSET AUTOSPARE 命令就可以了吗？

对，就是加上SET FAILEDSET AUTOSPARE 就行了。

谢谢，我会做一下试试的，结果也会告诉大家的！

我刚才运行了一下 set failedset autospare命令，但是发现做成spareset的磁盘根本没有替换一个raid中已经坏了的一块盘。

这个坏了的磁盘已经被我删掉拔出来了，并在原来的位置插进去一块好盘，作了一个spareset，原来raid中有三块盘，把这块坏了的删掉后就剩两块了，怕再坏一块就完了。请大家再指点一下，非常感谢！

对于已经做成spareset的磁盘，我是不是还少了什么操作啊？怎么还是不能自动去替换坏盘呢？

以下是show spareset 的信息

HSZ70 > show spareset
Name          Storageset                     Uses             Used by
------------------------------------------------------------------------------

SPARESET      spareset                       DISK40100
                                             DISK50200
Previous controller operation terminated by power failure.

以下是有坏盘的那个raid的信息

HSZ70 > show data2

        Switches:
          POLICY (for replacement) = BEST_PERFORMANCE
          RECONSTRUCT (priority) = NORMAL
          CHUNKSIZE = 256 blocks
        State:
          REDUCED
          DISK40200 (member  0) is NORMAL
          DISK60200 (member  2) is NORMAL
        Size: 142194506 blocks

以下是show failedset的信息

你的raid已经处于reduced的状态了，你可以用set data2 replace=disk*****命令，用和你坏掉那块盘一样容量的盘的代号。然后data2就应该开始重构了。

parker_73

还有，做之前可能要先把policy改成nopolicy，用set data2 nopolicy。同时替换的这块盘也不能是任何raid里的，也不能是spareset里的，先把那块替换的盘从spareset里删除了！

SET RAIDset-name
Changes the characteristics of a RAIDset.

Format
SET RAIDset-name

Parameters
RAIDset-name
The name of the RAIDset that will have its characteristics modified.

Switches
POLICY=BEST_FIT
POLICY=BEST_PERFORMANCE (Default)
NOPOLICY
Specifies the replacement policy to use when a member within the RAIDset fails.
Select BEST_FIT to choose a replacement device from the spareset that most closely matches
the capacities of the remaining members. If more than one device in the spareset is the
correct size, the controller selects the device that gives the best performance.
Select BEST_PERFORMANCE to choose a replacement device from the spareset that results in
the best performance (the device should be on a different port than existing members). If
more than one device in the spareset has the best performance, the controller selects the
device that most closely matches the size of the remaining members.
Select NOPOLICY to prevent the controller from replacing a failed disk drive. This causes the
RAIDset to run in a reduced state until a BEST_FIT or BEST_PERFORMANCE policy is selected,
or a member is manually replaced in the RAIDset (see SET RAIDset-name).
RECONSTRUCT=NORMAL (Default)
RECONSTRUCT=FAST
The RECONSTRUCT switch allows you to set the speed at which the controller reconstructs the
data on a new RAIDset member that has replaced a failed member.
Select NORMAL to balance other controller operations against the reconstruct operation. The
controller uses relatively few resources to perform the reconstruct, and there is little impact
on performance.
Select FAST when the reconstruct operation must take precedence over other controller
operations. The controller uses more resources and the reconstruct takes less time, but
overall controller performance is reduced during the reconstruct.

REPLACE=disk-name
__________________________ Note_____________________________
You cannot specify any other switches to the SET RAIDset-name command when
you use the REPLACE switch.
____________________________________________________________
Adds a disk drive into a reduced RAIDset. A reconstruct operation begins immediately on
the new drive. The RAIDset must be reduced (missing one member) and have NOPOLICY set.
The disk drive must not be in any configuration, including the spareset.

非常感谢，我试试看，试过后会报告结果的！

这位parker_73  朋友，能不能给解释一下，为什么原来已经有的那块spareset磁盘没有自动替换raid里坏掉的盘呢？而使得这个raid现在成了reduced状态.这个spareset磁盘是18G的，坏掉的是9G的，但是spareset是在坏掉之前就做好了的,我一直没搞明白它怎么没有自动替换
