设置共享磁盘的设备号遇到的问题
本帖最后由 davidh2y 于 2011-05-30 15:54 编辑2台hp机器，共享3颗磁盘：按照红宝书的prodedure 1操作后，结果如下：
root@test6:/>ioscan -f | grep -e INTERFACE -e DEVICE | grep -v target | awk '{print $3, $1, $2}'

可是从ioscan -m lun 返回的结果却不是预期结果：

执行ioscan -fnC disk返回的instance number相同，而ioscan -m lun返回的不同！
要如何正确设置，才能让ioscan -m lun返回相同的instance number? ioscan -n看的是legacy 的instance number
ioscan -m lun 看的是persistent的instance number
你想要哪种方式的instance number一致？ 本帖最后由 davidh2y 于 2011-05-31 13:30 编辑
需要persistent的instance number 设为一致。
顺便问一下，这2个有什么区别？ legacy设备文件是cxtxdx
persistent设备文件是diskx
persistent是hpux 11.31才有的，diskx其实是聚合的路径。
使用ioscan -m dsf 可以看到两者之间的关系。 本帖最后由 davidh2y 于 2011-05-31 17:32 编辑

要把/dev/rdsk/c4t1d0，/dev/rdsk/c4t2d0，/dev/rdsk/c4t3d0这2个永久设备号做成一样，该如何做？ 1、生成infile文件
# cd /tmp
# ioscan -kNf | grep ^disk | awk '{printf "%s %s %s\n",$3,$1,$2}' > infile
2、修改infile文件
3、执行ioinit，完成修改
# ioinit -f ./infile
4、删除原disk 本帖最后由 davidh2y 于 2011-06-01 14:42 编辑

执行步骤( 在test7执行)：
1. cd /tmp
ioscan -kNf | grep ^disk | awk '{printf "%s %s %s\n",$3,$1,$2}' > infile
2、修改infile文件
修改后的文件：
root@test7:/tmp>more infile
64000/0xfa00/0x1a disk 12
64000/0xfa00/0x1e disk 14
64000/0xfa00/0x1f disk 16
64000/0xfa00/0x20 disk 18
3、执行ioinit，完成修改
# ioinit -f ./infile
4.删除原disk
rmsf -x
执行后的结果：
ioscan -m lun
root@test7:/>ioscan -m lun

这里test6:instance number和/dev/disk/diskNN编号一致，而test7:instance number 却和/dev/disk/diskNN 不一致。
导致最后安装11g 的clusterware 报错。
安装过程中选择disk 18（diskgroup :crs_dg）作为默认的dg(存放ocr和voting disk).
test6 执行root.sh成功，test7执行root.sh报错，“Timed out waiting for the CRS stack to start”
查crsd.log：OCR context init failure.Error: PROC-26: Error while accessing the physical storage ASM error [SLOS: cat=8, opn=kgfo
OpenFile01, dep=15056, loc=kgfokge
查alerttest7.log :The OCR location in an ASM disk group is inaccessible
我怀疑是在test7的编号不一致导致？如何处理，让test7的ioscan -m lun输出和test6的完全一样（在共享磁盘）。 rmsf /dev/disk/disk13

相同的instance number 14,可是test6 为64000/0xfa00/0x22，而test7为64000/0xfa00/0x1e。如何设为一致？ 这个改不了的，和设备硬件有关。
