IBM ds3512在sm管理误删了raid，有办法恢复吗？

之前要的一次故障解决方法，看是否可以帮到你。

环境：RAC for POWER520*2+DS4700
系统：AIX5.3
应用：RAC 10G
故障：
存储显示B控温度传感器故障，Cache电池故障，经排查怀疑为B控制器故障

更换存储控制器后，存储配置丢失如图：

解决：
1.根据存储提示处理报错
2.根据recoveryProfile.csv文件提取RAID配置，具体方法如下：

解析：

VolumeGroup 行是raid的信息：

Volume 行是lun信息
lun的信息如下：
各行解释如下：
Object type (volume, volume group, etc.)
Volume NAA ID
Volume name
Owning array NAA ID
Block size (typically 512; this might be 4096 on SSD or high-capacity disks with 4k blocks, but I have none of these to test with)
LUN size in bytes
Starting offset; on this LUN the unit appears to be (bytes / 2048) but I can’t figure out why
Segment size in bytes
Two integers/booleans I haven’t identified

RAID5_2 恢复

set storageSubsystem mediaScanRate=disabled;

recover logicaldrive drives=(85,7 85,8 85,9 85,10 85,11 85,12 ) newVolumeGroup="RAID5-2" userLabel= "DA_file5"   capacity=322122547200 offset=0 raidLevel=5 
segmentSize=128 owner=a;
recover logicaldrive array="RAID5-2" userLabel="DA_file6" capacity=322122547200 offset=125829120 raidLevel=5 segmentSize=128 owner=b;
recover logicaldrive array="RAID5-2" userLabel="DA_file7" capacity=322122547200 offset=251658240 raidLevel=5 segmentSize=128;
recover logicaldrive array="RAID5-2" userLabel="DA_file8" capacity=515396075520 offset=377487360 raidLevel=5 segmentSize=128 owner=b;

注意：drives=(85,1 85,2 85,3 85,4 85,5 )的顺序一定要对，否则LUN的数据有问题。这个顺序recoveryProfile中描述的是不正确的，按storageArrayProfile文件中的顺序。各个array的创建顺序也要按storageArrayProfile来创建。

常规的手段好像不行。因为只是删除了RAID信息。所以通过数据恢复。重建RAID序列是没什么大问题的
但是sm本身好像删除了就删除了吧。

你换控制器怎么会丢失信息呢？换B控制器，将卷都切到A上面。
你操作又没有问题哦
