Itanium定位盘位:sasmgr set_attr -D /dev/sasd0 -q lun=/dev/rdsk/c*t*d* -q locate_led=on
1、传统方法换根盘(拆mirror,建mirror)

replace disk
=========================
IA 机器上创建根盘镜像
vi /tmp/idf

EFI 500MB
HPUX 100%
HPSP 400MB
idisk -f /tmp/idf -w /dev/rdisk/disk5
/*创建分区文件,以及对pv 进行分区,可以用两条命令替代 。print '3\nEFI 500MB\nHPUX 100%\nHPSP 400MB' > /tmp/idf echo yes | idisk -wf /tmp/idf /dev/rdisk/disk5

lvsync -T /dev/vg00/lvol*
lvlnboot -R -v /dev/vg00
setboot -a /dev/disk/disk5_p2
vi /stand/boot.conf
l /dev/disk/disk5_p2
2 、使用LVM OLR 更换根盘
HP-UX 使用LVM OLR 更换根盘
说说另外一种更换root disk(mirror)的方法
HP-UX 11.11 以及11.23 只有在安装以下补丁后,才支持LVM OLR For 11.11: Patches PHKL_31216 and PHCO_30698
For 11.23: Patches PHKL_32095 and PHCO_31709
HP-UX 11.31 不需要任何补丁,就能支持OLR
或者也可以通过man,查看pvchange 有没有-a 的参数,如果没有只能使用拆mirror,创建mirror 的方法更换root disk
更换步骤:
PA 更换根盘(OLR)
pvchange -a N /dev/dsk/cxtxdx
=========================
replace disk
=========================
insf -eH path
vgcfgrestore -n vg00 /dev/rdsk/cxtxdx
pvchange -a y /dev/dsk/cxtxdx
vgsync
mkboot /dev/rdsk/cxtxdx
mkboot -a "hpux" /dev/rdsk/cxtxdx
lvlnboot -R -v/dev/vg00
setboot -a path
# vi /stand/bootconf
l /dev/dsk/cxtxdx -------------------------------------------------
IA 更换根盘(OLR)

idisk -f /tmp/idf -w /dev/rdisk/disk5

lvlnboot -R -v /dev/vg00
setboot -a path
# vi /stand/bootconf
l /dev/disk/disk5_p2
