HP-UNIX 创建文件系统

1.系统环境
# uname -a
HP-UX callcdb2 B.11.31 U ia64 
2.查看VG组
# ll /dev/vg*/group
crw-r-----   1 root       sys         64 0x000000 Jun  9 12:13 /dev/vg00/group
3.创建物理卷
# pvcreate /dev/rdisk/disk162
Physical volume "/dev/rdisk/disk162" has been successfully created.
4.创建VG
4-1.创建VG组名
# mkdir /dev/vg_cdc
# ll /dev/vg*/group
crw-r-----   1 root       sys         64 0x000000 Jun  9 12:13 /dev/vg00/group
4-2.给与VG组唯一的0x010000
# mknod /dev/vg_cdc/group c 64 0x010000
#  ll /dev/vg*/group
crw-r-----   1 root       sys         64 0x000000 Jun  9 12:13 /dev/vg00/group
crw-r--r--   1 root       sys         64 0x010000 Aug 18 14:19 /dev/vg_cdc/group
4-3.创建VG组并写入配置文件
# vgcreate -s 32 /dev/vg_cdc /dev/disk/disk162
Increased the number of physical extents per physical volume to 1599.
Volume group "/dev/vg_cdc" has been successfully created.
Volume Group configuration for /dev/vg_cdc has been saved in /etc/lvmconf/vg_cdc.conf
5.创建LV并指定LV大小
# lvcreate -L 40000 -n lv_cdc  vg_cdc
Logical volume "/dev/vg_cdc/lv_cdc" has been successfully created with
character device "/dev/vg_cdc/rlv_cdc".
Logical volume "/dev/vg_cdc/lv_cdc" has been successfully extended.
Volume Group configuration for /dev/vg_cdc has been saved in /etc/lvmconf/vg_cdc.conf
6.格式化
# newfs -F vxfs -o largefiles /dev/vg_cdc/rlv_cdc
    version 7 layout
    40960000 sectors, 40960000 blocks of size 1024, log size 65536 blocks
    largefiles supported
7.创建挂载点
# mkdir /cdc
8.挂载
# mount /dev/vg_cdc/lv_cdc /cdc

附表
1.vgexport vg_cdc --删除VG卷组
2.pvcreate -f  /dev/rdisk/disk162  --如果重新创建VG卷组的时候加F参数
3.vgchange -a n(y) vg_cdc    --停止或者激活逻辑卷组。

换SAS卡、重启后出现此问题。重新激活逻辑卷组即可
vgdisplay: Volume group not activated.
vgdisplay: Cannot display volume group "/dev/vg_cdc".

解决方法：vgchange -a y /dev/vg_cdc
