1、reserve_policy 可能存在问题
To enable simultaneous access to a disk device from multiple nodes, you must set the appropriate Object Data Manager (ODM) attribute listed in the following table to the value shown, depending on the disk type:
Disk Type Attribute Value
SSA or FAStT disks reserve_lock no
ESS, EMC, HDS, CLARiiON, or MPIO-capable disks reserve_policy no_reserve
To determine whether the attribute has the correct value, enter a command similar to the following on all cluster nodes for each disk device that you want to use:
# /usr/sbin/lsattr -E -l hdiskn
If the required attribute is not set to the correct value on any node, enter a command similar to one of the following on that node:
SSA and FAStT devices:
# /usr/sbin/chdev -l hdiskn -a reserve_lock=no
ESS, EMC, HDS, CLARiiON, and MPIO-capable devices:
# /usr/sbin/chdev -l hdiskn -a reserve_policy=no_reserve
