1.ioscan -funNC disk显示出聚合后的硬件路径，如：
disk    85  64000/0xfa00/0x14  esdisk CLAIMED    DEVICE    HP 146 GST3146855LC
                  /dev/disk/disk85    /dev/disk/disk85_p2 /dev/rdisk/disk85    /dev/rdisk/disk85_p2
                  /dev/disk/disk85_p1 /dev/disk/disk85_p3 /dev/rdisk/disk85_p1  /dev/rdisk/disk85_p3
disk    86  64000/0xfa00/0x15  esdisk CLAIMED    DEVICE    HP 36.4GST336753LC
                  /dev/disk/disk86 /dev/rdisk/disk86
disk 156  64000/0xfa00/0x23  esdisk NO_HW    DEVICE    HP    HSV200
                  /dev/disk/disk156    /dev/disk/disk156_p2 /dev/rdisk/disk156    /dev/rdisk/disk156_p2
                  /dev/disk/disk156_p1 /dev/disk/disk156_p3 /dev/rdisk/disk156_p1  /dev/rdisk/disk156_p3

2.使用ioscan -m hwpath -H 64000/0xfa00/0x14确定此lun下包含的每一条lunpath H/W path。如：
#rx8640[/]#ioscan -m hwpath -H 64000/0xfa00/0x12
Lun H/W Path    Lunpath H/W Path                Legacy H/W Path
====================================================================
64000/0xfa00/0x12
               0/0/6/1/0.0x50001fe1500958c9.0x400e000000000000
               0/0/6/1/0.0x50001fe1500958cc.0x400e000000000000
               0/0/6/1/0.0x50001fe1500958c8.0x400e000000000000
               0/0/6/1/0.0x50001fe1500958cd.0x400e000000000000
               0/0/14/1/0.0x50001fe1500958cc.0x400e000000000000
               0/0/14/1/0.0x50001fe1500958c8.0x400e000000000000
               0/0/14/1/0.0x50001fe1500958cd.0x400e000000000000
               0/0/14/1/0.0x50001fe1500958c9.0x400e000000000000

3.使用ioscan -P health -H 0/0/6/1/0.0x50001fe1500958c9.0x400e000000000000检查此条路径的健康性。如：
rx8640[/]#ioscan -P health -H 0/0/6/1/0.0x50001fe1500958c9.0x400e000000000000
Class    I  H/W Path  health
