AIX磁盘锁

问题情况：原2台服务器做HA，业务需要重做系统后存储上的几块盘不认PVID，并且不能使用chdev -l hdiskx -a pv=yes获得PVID，存储上无锁（Advanced->Maintenance->Persistent Reservations）想从存储中删除LP也报错

Reason: Reserved
Recovery steps: Release through application and retry

# chdev -l hdisk1 -a pv=yes
Method error (/usr/lib/methods/chgdisk):
        0514-047 Cannot access a device.

 

解决办法：

#lsattr -El hdisk2

修改reserve_policy single_path为reserve_policy no_reserve

chdev -l hdiskx -a reserve_policy=no_reserve
