如何更换LSM中坏的mirror disk
Here is an LSM doc that I had. Just replace rz9 with rz8 in it.
LSM - Replacing a Failed Disk
=============================
· Delete the failed disk, for example rz9 from the disk group retaining the media
records. Use the disk media name.
# /sbin/voldg -g rootdg -k rmdisk disk09b
rmdisk
Removes the specified disk(s) from a disk group (rootdg by default).
The last disk cannot be removed from its disk group. It is not possible
to remove the last disk containing a valid disk group configuration or
log copy from its disk group.
Normally, the rmdisk operation will fail if subdisk records point to
the named disk media records. However, if the -k option is specified,
the disk media records will be kept, although in a removed state, and
the subdisk records will still point to them. The subdisks, and any
plexes that refer to them, are unusable until the disk is re-added
using the -k option to the adddisk operation. Any volumes that become
unusable, because all plexes become unusable, will be disabled.
Note
Use extra care with the -k option since this option can disable
active volumes.
· Remove the disk access records, using the disk access name.
# /sbin/voldisk rm rz9b
· Physically replace the failed disk with a new disk.
· Disk label the new disk.
· Initialize the new disk for use by LSM.
# /usr/sbin/voldisksetup -i rz9b nconfig=2 nlogs=2 privlen=1024
-i Normally, voldisksetup simply creates partitions for use with the Logi-
cal Storage Manager. If the -i (initialize) option is specified, a disk
header is added and an empty configuration is written on the disk. This
operation destroys any previous LSM database contents on the disk.
· Add the new disk to the disk group.
# /sbin/voldg -g rootdg -k adddisk disk09b=rz9b
· If this is a mirrored volume, attach the stale plex, start the volume, and start recovery.
# volrecover -sb vol-01
-s Starts di

如何更换LSM中坏的mirror disk
you have to provide more information for troubleshooting, for example, do you have hot-
sparing feature enabled in your rootdg ? or the output of your `voldisk list` and anyother warning, error in your system messages file.

如何更换LSM中坏的mirror disk
非常谢谢两位老兄:
上面的文档应该只是针对更换坏盘不,但不是更换坏的mirror盘的,所以这个方案我觉得不大妥。看了LSM的文档,里面也没有讲怎么更换。
