本文介绍了在HP-UX系统中如何进行LVM(Logical Volume Manager)配置的详细步骤，包括创建物理卷(PV)、卷组(VG)及逻辑卷(LV)，并演示了如何使用vxfs文件系统进行格式化。

1.查看主机
# uname -a
HP-UX hp1131 B.11.31 U ia64 0587810598 unlimited-user license
#

2.查看硬盘大小
# ioscan -fnCdisk
Class I H/W Path Driver S/W State H/W Type Description
=======================================================================
disk 2 0/0/2/0.0.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-B
/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0
disk 0 0/1/1/0.0.0 sdisk CLAIMED DEVICE FUJITSU MAP3147NC
/dev/dsk/c2t0d0 /dev/dsk/c2t0d0s2 /dev/rdsk/c2t0d0 /dev/rdsk/c2t0d0s2
/dev/dsk/c2t0d0s1 /dev/dsk/c2t0d0s3 /dev/rdsk/c2t0d0s1 /dev/rdsk/c2t0d0s3
disk 1 0/1/1/0.1.0 sdisk CLAIMED DEVICE FUJITSU MAP3147NC
/dev/dsk/c2t1d0 /dev/rdsk/c2t1d0
disk 24 0/2/1/0.1.11.255.0.0.0 sdisk CLAIMED DEVICE EP-2123Ssun480
/dev/dsk/c9t0d0 /dev/rdsk/c9t0d0
disk 25 0/2/1/0.1.11.255.0.0.1 sdisk CLAIMED DEVICE EP-2123S4up270
/dev/dsk/c9t0d1 /dev/rdsk/c9t0d1
disk 26 0/2/1/0.1.11.255.0.0.2 sdisk CLAIMED DEVICE EP-2123S2up270
/dev/dsk/c9t0d2 /dev/rdsk/c9t0d2
disk 22 0/2/1/0.1.13.255.0.0.0 sdisk CLAIMED DEVICE EP-2123Shp1123
/dev/dsk/c8t0d0 /dev/rdsk/c8t0d0
disk 23 0/2/1/0.1.13.255.0.0.1 sdisk CLAIMED DEVICE EP-2123Shp1131
/dev/dsk/c8t0d1 /dev/rdsk/c8t0d1

3.查看硬盘信息:
# diskinfo -v /dev/rdsk/c8t0d1
SCSI describe of /dev/rdsk/c8t0d1:
vendor: EP-2123S
product id: hp1131
type: direct access
size: 488279808 Kbytes
bytes per sector: 512
rev level: R001
blocks per disk: 976559616
ISO version: 0
ECMA version: 0
ANSI version: 5
removable media: no
response format: 2
(Additional inquiry bytes: (32)72 (33)65 (34)63 (35)61 (36)20 (37)41 (38)52 (39)43 (40)4b (41)49 (42)20 (43)44 (44)65 (45)76 (46)69 (47)63 (48)65 (49)20 (50)20 (51)f (52)0 (53)0 (54)0 (55)0 (56)0 (57)0 (58)0 (59)0 (60)0 (61)0 (62)0 (63)0 (64)0 (65)0 (66)0 (67)0 (68)0 (69)0 (70)0 (71)0 (72)0 (73)0 (74)0 (75)0 (76)0 (77)0 (78)0 (79)0 (80)0 (81)0 (82)0 (83)0 (84)0 (85)0 (86)0 (87)0 (88)0 (89)0 (90)0 )
#
#

4.加-f 参数强制建pv:
# pvcreate -f /dev/rdsk/c8t0d1
Physical volume "/dev/rdsk/c8t0d1" has been successfully created.
#

5.创建vg目录:
# mkdir /dev/datavg
#

6.
mknod /dev/datavg/group c 64 0x090000

7.创建对于大于256G的硬盘的VG时候,需加参数-s 8
# vgcreate -s 8 datavg /dev/dsk/c8t0d1
Increased the number of physical extents per physical volume to 59604.
Volume group "/dev/datavg" has been successfully created.
Volume Group configuration for /dev/datavg has been saved in /etc/lvmconf/datavg.conf
#

8. 创建LV
# lvcreate -L 102400 -n lvdsg11 /dev/datavg
Logical volume "/dev/datavg/lvdsg11" has been successfully created with
character device "/dev/datavg/rlvdsg11".
Logical volume "/dev/datavg/lvdsg11" has been successfully extended.
Volume Group configuration for /dev/datavg has been saved in /etc/lvmconf/datavg.conf
# lvcreate -L 102400 -n lvdsg10 /dev/datavg
Logical volume "/dev/datavg/lvdsg10" has been successfully created with
character device "/dev/datavg/rlvdsg10".
Logical volume "/dev/datavg/lvdsg10" has been successfully extended.
Volume Group configuration for /dev/datavg has been saved in /etc/lvmconf/datavg.conf
#

9.格式化文件系统:

# newfs -F vxfs /dev/datavg/rlvdsg10
version 6 layout
106496 sectors, 106496 blocks of size 1024, log size 1024 blocks
largefiles supported
# newfs -F vxfs /dev/datavg/rlvdsg11
version 6 layout
106496 sectors, 106496 blocks of size 1024, log size 1024 blocks
largefiles supported
#

10.

# mount /dev/datavg/lvdsg10 /dsg10
# mount /dev/datavg/lvdsg11 /dsg11
