hp-ux 系统NO_HW盘解决方法
在某此情况下，HP-UX系统上ioscan后容易出现NO_HW状态的盘，比如：
RX2604[/#]ioscan -fNnkC disk

RX2604[/#]
这种情况的出现是因为，disk28和disk29这2块盘之前有使用，后来在HP p2000的存储上删除重新划掉过，而disk34和disk35是新盘，在这台服务器上以前未使用过，所以状态是正常的。
出现这种情况，通常重新HP-UX系统后再重新用ioscan扫描后可解决，当不能重启时，使用以下方法：
rmsf -k -H hw_path
使用以下命令可清除所有的NO_HW的盘：
ioscan -nfC disk|grep NO_HW|awk '{print $3}'|xargs -i -t rmsf -H {}
一个例子：
RX2604[/#]ioscan -nfC disk|grep NO_HW|awk '{print $3}'|xargs -i -t rmsf -H {}
rmsf -H 0/4/0/0/0/0.2.14.0.0.0.1
rmsf -H 0/4/0/0/0/0.2.14.0.0.0.2
rmsf -H 0/4/0/0/0/1.2.14.0.0.0.1
rmsf -H 0/4/0/0/0/1.2.14.0.0.0.2
