HP-UX 修改disk instance號

1.可以在2臺主機上透過scsimgr -p get_attr all_lun -a hw_path -a device_file -a wwid來檢視wwn，wwn一致的為同一個盤，也可以透過它與儲存劃得每個lun對應起來
2.透過ioinit來修改，具體過程如下：

備份先：備份ioconfig及ioscan的輸出

更改過程
# ioscan –funNCdisk

Class I H/W Path Driver S/W State H/W Type Description
===================================================================
...
disk 17 64000/0xfa00/0xb esdisk CLAIMED DEVICE HP EF0300FATFD
/dev/disk/disk17 /dev/rdisk/disk17
現在要將disk17改為disk28，因為我僅僅是要修改一個disk，所以就直接vi一個infile檔案，如果disk比較多，ioscan加awk來做
#cat infile
64000/0xfa00/0xb disk 28
這裡的64000/0xfa00/0xb是ioscan裡面的disk17的H/W Path
# ioinit -f infile
# ioscan -funNCdisk
Class I H/W Path Driver S/W State H/W Type Description

disk 28 64000/0xfa00/0xb esdisk CLAIMED DEVICE HP EF0300FATFD
/dev/disk/disk17 /dev/disk/disk28 /dev/rdisk/disk17 /dev/rdisk/disk28
# rmsf /dev/disk/disk17
# rmsf /dev/rdisk/disk17

# ioscan -funNCdisk
Class I H/W Path Driver S/W State H/W Type Description

disk 28 64000/0xfa00/0xb esdisk CLAIMED DEVICE HP EF0300FATFD

主機重啟後disk instance number不會發生變化
