现象:
在aix系统中,lspv:# lspv
hdisk0 00f66a03dbeaedf1 rootvg active
hdisk1 none None
hdisk2 none None
hdisk3 none None
hdisk4 none None
hdisk5 none None
hdisk6 none None
能看到多余的6个盘,是我从emc挂载上来的。
但是lspath就感觉有问题:
# lspath
Enabled hdisk0 vscsi0
没有hdisk1到6的磁盘信息。说明mpio根本没认。
#lsdev -Cc disk
hdisk0 Available Virtual SCSI Disk Drive
hdisk1 Available 00-00-02 Other FC SCSI Disk Drive
hdisk2 Available 00-00-02 Other FC SCSI Disk Drive
hdisk3 Available 00-00-02 Other FC SCSI Disk Drive
hdisk4 Available 00-00-02 Other FC SCSI Disk Drive
hdisk5 Available 00-00-02 Other FC SCSI Disk Drive
hdisk6 Available 00-00-02 Other FC SCSI Disk Drive
所以我想修改hdisk1-6的reserve_policy属性也是不行的,因为根本就没有这个参数,lsattr -El hdisk1
# lsattr -El hdisk1
clr_q no Device CLEARS its Queue on error True

请问下,这个该怎么解决?我没有powepath,我想用mpio来做,请教怎么处理?
