寻找sun官方文档《cluster 3.x下如何重建全局设备》
请问哪位兄弟有sun官方的文档《Sun Cluster 3.x: What to do if the /global/.devices/node@X filesystem needs rebuilding》文档id：79281
谢谢 sun网站上找找？ # Comment out the /global/.devices/node@2 line in /etc/vfstab
# # shutdown -g0 -y -i0
OK boot -sx
# # newfs /dev/vx/rdsk/node@2
# Uncomment /global/.devices/node@2 in vfstab
# # reboot 留个脚印，还是蜘蛛老大厉害，下个月要有个suncluster项目要做，可能用得到 谢谢蜘蛛，这个文档不知道怎么的，在sun上找不到了
回复 #3 东方蜘蛛 的帖子
另外请教蜘蛛，我双机中的备机全局设备出现问题，挂接或者对其操作就报I/O ERROR，不知道是否可以照这个方法重建全局设备。相关信息如下：#df -k

scdidadm -C
scdidadm -r
scgdevs 请问蜘蛛老大，对现网业务执行以上是否会有影响?谢谢 双机都做了蜘蛛兄所说的，问题依旧！这个东东看来难整了 我遇到这问题用了蜘蛛的方法能够看到了
