HP v11.23下完全清除硬盤(pán)殘留的分區(qū)信息

penguinstorm

如下所示，HP 11.23操作系統(tǒng)中，一次鏡像分拆后，/dev/dsk/c5t0d0磁盤(pán)上(原系統(tǒng)鏡像盤(pán))仍舊留有和系統(tǒng)盤(pán)/dev/dsk/c0t6d0相同的分區(qū)信息:

僅僅通過(guò)“pvcreate -f /dev/rdsk/c5t0d0”來(lái)對(duì)磁盤(pán)進(jìn)行格式化也只能對(duì)磁盤(pán)中數(shù)據(jù)進(jìn)行清空，但分區(qū)信息依然存在:
# pvcreate -f /dev/rdsk/c5t0d0
Physical volume "/dev/rdsk/c5t0d0" has been successfully created.
# ioscan -fnC disk

下面介紹清空分區(qū)信息的具體方法：
1，# idisk -R /dev/rdsk/c5t0d0
idisk version: 1.32
********************** WARNING ***********************
If you continue you will destroy all partition data on this disk.
Do you wish to continue(yes/no)? yes
2，# rmsf -H 2/0/12/1/0/4/1.0.0
3， ioscan -fnC disk

通過(guò)以上信息可見(jiàn)磁盤(pán)/dev/dsk/c5t0d0上分區(qū)信息已經(jīng)丟失，磁盤(pán)路徑?jīng)]有顯示是與"rmsf -H 2/0/12/1/0/4.1.0.0"有關(guān)；
4，通過(guò)"insf"命令為磁盤(pán)加載驅(qū)動(dòng)程序：
