求助SVM metasat 里面看不硬盘id 号
各位好，最近在处理一490硬盘故障，发现 metastat里面看不到 c1t1d0硬盘id号，Rolc 的状态为:no，但是format 能看到硬盘id 号。另外，现在c1t0d0硬盘大量坏道读写报错，需要更换，现在metastat 镜像状态都ok，但是看不到c1t1d0的硬盘id ，不敢轻易更换c1t0d0，还请各位给个建议。目前硬盘从c1t0d0启动。bash-2.05# metadb

各位大神 ，路过帮忙瞧瞧，给个建议啊 。:em03::em03::em03::em03: 那就先用 metadevadm-u c1t1d0刷新一下硬盘id。。 metadevadm 试过了，没反应啊，还是看不到ID回复 5# ericyan_cu
系统是solaris 9 u8，如果补丁之类没打齐全的话会出现过这种情况吗？有没碰到类似情况。回复 5# ericyan_cu
最好先做好备份，然后再经行尝试。如果换盘的话，先换读写错误最多的那个。 担心受到devid的影响，那就考虑禁用了。
Before:
# Begin MDD database info (do not edit)
...
# End MDD database info (do not edit)
After:
md_devid_destroy=1;
md_keep_repl_state=1;
# Begin MDD database info (do not edit)
...
# End MDD database info (do not edit) 正常重启一次，。。就ok了
