楼主

1.可以在2台主机上通过scsimgr -p get_attr all_lun -a hw_path -a device_file -a wwid来查看wwn，wwn一致的为同一个盘，也可以通过它与存储划得每个lun对应起来
2.通过ioinit来修改，具体过程如下：

备份先：备份ioconfig及ioscan的输出

更改过程

# ioscan –funNCdisk

disk 17 64000/0xfa00/0xb esdisk CLAIMED DEVICE HP EF0300FATFD
/dev/disk/disk17 /dev/rdisk/disk17

现在要将disk17改为disk28，因为仅仅是要修改一个disk，所以就直接vi一个infile文件，如果disk比较多，ioscan加awk来做

#cat infile
64000/0xfa00/0xb disk 28

这里的64000/0xfa00/0xb是ioscan里面的disk17的H/W Path

# ioinit -f infile
# ioscan -funNCdisk

主机重启后disk instance number不会发生变化
