配置SG的共享磁盘时，vgimport报错，该如何处理？

davidh2y

两台hp 服务器(test4和test5)，按如下配置vg:
test4执行:
pvcreate -f /dev/rdisk/disk36    --3G ，作为锁盘
pvcreate -f /dev/rdisk/disk37
mkdir /dev/dcracvg
mknod /dev/dcracvg/group c 64 0x060000
mkdir /dev/lockvg
mknod /dev/lockvg/group c 64 0x040000

导出 volume group
# vgchange -a n /dev/dcracvg
# vgchange -a n /dev/lockvg

# vgexport -v -p -s -m /tmp/dcracvg.map /dev/dcracvg
# vgexport -v -p -s -m /tmp/lockvg.map /dev/lockvg
                                
rcp /tmp/dcracvg.map test5:/tmp/                        
rcp /tmp/lockvg.map test5:/tmp/                        

test5执行:
# mkdir /dev/dcracvg
# mkdir /dev/lockvg
# mknod /dev/dcracvg/group c 64 0x060000
# mknod /dev/lockvg/group c 64 0x040000
# vgimport  -v -s -m /tmp/dcracvg.map -N /dev/dcracvg 报错

Beginning the import process on Volume Group "dcracvg".
Couldn't access the list of physical volumes for volume group "/dev/dcracvg".

其中test4看到的磁盘如下：
root@test4:/dev>ioscan -P wwid|grep disk
disk        36  64000/0xfa00/0x10  0x600508b4000cc9a80000e00002520000
disk        37  64000/0xfa00/0x11  0x600508b4000cc9a80000e00002580000
root@test5:/dev>ioscan -P wwid|grep disk
disk        36  64000/0xfa00/0x21  0x600508b4000cc9a80000e00002520000
disk        37  64000/0xfa00/0x22  0x600508b4000cc9a80000e00002580000

该如何解决呢？

对应的ioscan:
test4:
root@test4:/dev>ioscan -m dsf
Persistent DSF           Legacy DSF(s)
========================================
/dev/rdisk/disk36        /dev/rdsk/c0t0d1
/dev/rdisk/disk37        /dev/rdsk/c0t1d1

test5:
root@test5:/dev>ioscan -m dsf
Persistent DSF           Legacy DSF(s)
========================================
/dev/rdisk/disk36        /dev/rdsk/c4t4d0
/dev/rdisk/disk37        /dev/rdsk/c4t5d0

但如果使用如下

查看lvmtab

/dev/vg00
/dev/disk/disk11_p2
/dev/dcracvg
/dev/dsk/c4t5d0

发现和test4的不一样：
root@test4:/tmp>strings /etc/lvmtab
/dev/vg00
/dev/disk/disk20_p2
/dev/disk/disk21
/dev/vg_dljj
/dev/disk/disk25
/dev/lockvg
/dev/disk/disk36
/dev/dcracvg
/dev/disk/disk37

fruitmantis

直接指定pv

davidh2y

fruitmantis:能否更详细的说一下？谢谢！

fengshen518

vgimport –N              Configure the volume group using persistent DSFs. You can only use this

                           option together with the scan option, –s. In the absence of the -N
                           option, legacy DSFs are used.

fengshen518

你的系统是11.31的吗？  vgimport -N  这个参数好像是在31上才有的

davidh2y

11.31，看来不能用-N参数

lbseraph

看了下过程，LZ在vgexport的时候都没有用-N，vgimport的时候怎么用-N？可以重新试一下~

princeduan

大写N是在HP-UX 11i v3版本中使用的新选项。
通过lvmtab文件可以看出两种设备文件表示方式的不同。

11i v3以前
/dev/dsk/cxtxdx
/dev/rdsk/cxtxdx

11i v3
/dev/disk/diskx
/dev/rdisk/diskx

另外，见过以下用法。*N的位置有些不同。
vgimport -v -s -N -m /tmp/vg01_mapfile /dev/vg01
