环境: 操作系统AIX5.3,HA 5.4 IBM P52A机器 分别为APP和DB主机,各自有自己的资源组 EMC磁阵 该系统运行着重要业务
操作目的: 为HA双机(P52A机型)增加SCSI卡,以连接外置磁带机
操作步骤:先将DB主机切换到APP,DB释放资源组和IP,由APP主机接管.操作成功,然后DB主机关机,装SCSI卡.DB关机之后,先将DB上光纤\电源线\网线\心跳线都给拔下来了,安装上SCSI卡后,又重新接上.位置都没有接错.重起DB主机,接磁带机,磁带机正常.起DB系统双机软件,报错:
ERROR: Cluster verification detected that some of the disks on the cluster
use both hdisks and device paths on different nodes. To ensure correct
device processing, please confgure all nodes to use either hdisk
or vpath devices for the following PVIDs:
