redhat 7.x 、redhat 6.x查看硬盘UUID方法

程序员文章站 2023-11-06 08:10:58
1、查看磁盘分区UUID： [root@rac01 ~]# blkid /dev/sdb1: UUID="6bba92c4-0b25-4cc4-9442-ca87c563720a" TYPE="xfs" /dev/sda1: UUID="21b2b922-fcb7-461f-bdc6-3bd9225 ......

1、查看磁盘分区uuid：

[root@rac01 ~]# blkid
/dev/sdb1: uuid="6bba92c4-0b25-4cc4-9442-ca87c563720a" type="xfs" 
/dev/sda1: uuid="21b2b922-fcb7-461f-bdc6-3bd92259f8d7" type="xfs" 
/dev/sda2: uuid="wc12xe-0neg-kmhp-u691-8bxn-8ppf-pugghh" type="lvm2_member" 
/dev/mapper/rhel-root: uuid="774aa4fa-2bbe-4636-a3ce-3a8aec9cdb40" type="xfs" 
/dev/mapper/rhel-swap: uuid="01075670-9314-4899-8d0f-23af11882416" type="swap" 
/dev/sr0: uuid="2016-10-19-18-32-06-00" label="rhel-7.3 server.x86_64" type="iso9660" pttype="dos" 
[root@rac01 ~]#

 

[root@rac01 ~]# ls -l /dev/disk/by-uuid/
total 0

2、查看磁盘uuid

 

[root@rac01 ~]# lsscsi -i

[root@rac01 ~]#

 

使用/lib/udev/scsi_id查看磁盘uuid

[root@rac01 ~]# /lib/udev/scsi_id --help
usage: scsi_id [option...] device
scsi device identification.
  -h --help                        print this message
    --version                     print version of the program
  -d --device=                     device node for sg_io commands
  -f --config=                     location of config file
  -p --page=0x80|0x83|pre-spc3-83  scsi page (0x80, 0x83, pre-spc3-83)
  -s --sg-version=3|4              use sgv3 or sgv4
  -b --blacklisted                 treat device as blacklisted
  -g --whitelisted                 treat device as whitelisted
  -u --replace-whitespace          replace all whitespace by underscores
  -v --verbose                     verbose logging
  -x --export                      print values as environment keys
[root@rac01 ~]#

 

命令：/lib/udev/scsi_id --whitelisted --device=/dev/sd*

[root@rac01 ~]# /lib/udev/scsi_id --whitelisted --device=/dev/sdc
36000c29cd6841d61d151f17cfaae37c1
[root@rac01 ~]# /lib/udev/scsi_id --whitelisted --device=/dev/sdd
36000c29981370abb4b6dbf6101ad8e9f
[root@rac01 ~]# /lib/udev/scsi_id --whitelisted --device=/dev/sde
36000c29b71c709b99b63547534028558
[root@rac01 ~]# /lib/udev/scsi_id --whitelisted --device=/dev/sdf
36000c29bbaf58c22dcb92b6f6e4c67e9
[root@rac01 ~]# /lib/udev/scsi_id --whitelisted --device=/dev/sdg
36000c2942fbfb7d286d52d2e7fa5cf05
[root@rac01 ~]# /lib/udev/scsi_id --whitelisted --device=/dev/sdh
36000c29ac6f46745dccdcb2e623064da
[root@rac01 ~]#

 

******************************************************************************

注：

redhat 6.x命令为:

scsi_id --whitelisted --device=/dev/sd*

******************************************************************************

 

3、使用脚本输入磁盘uuid

符号“c d e f g h”为磁盘名

linux 7.x脚本为

[root@rac01 ~]# for i in c d e f g h; 
> do 
> echo "sd$i" "`/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i` "; 
> done
sdc 36000c29cd6841d61d151f17cfaae37c1 
sdd 36000c29981370abb4b6dbf6101ad8e9f 
sde 36000c29b71c709b99b63547534028558 
sdf 36000c29bbaf58c22dcb92b6f6e4c67e9 
sdg 36000c2942fbfb7d286d52d2e7fa5cf05 
sdh 36000c29ac6f46745dccdcb2e623064da 
[root@rac01 ~]#

 

******************************************************************************

注：

linux 6.x脚本为

> do 
> echo "sd$i" "`scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i` "; 
> done
sdc 36000c29cd6841d61d151f17cfaae37c1 
sdd 36000c29981370abb4b6dbf6101ad8e9f 
sde 36000c29b71c709b99b63547534028558 
sdf 36000c29bbaf58c22dcb92b6f6e4c67e9 
sdg 36000c2942fbfb7d286d52d2e7fa5cf05 
sdh 36000c29ac6f46745dccdcb2e623064da 
[root@rac01 ~]#

4、oracle asm配置

生成文件内容的脚本

 

for i in c d e f g h;
do
echo "kernel==\"sd*\",bus==\"scsi\", program==\"/lib/udev/scsi_id --whitelisted --replace-whitespace--device=/dev/\$name\", result==\"`/lib/udev/scsi_id --whitelisted--replace-whitespace --device=/dev/sd$i`\", name=\"asm-disk$i\",owner=\"grid\", group=\"asmadmin\",mode=\"0660\""     
done
 
[root@rac01 ~]# for i in c d e f g h;
> do
> echo "kernel==\"sd*\", bus==\"scsi\", program==\"/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", result==\"`/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\", name=\"asm-disk$i\", owner=\"grid\", group=\"asmadmin\", mode=\"0660\""      
> done
kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c29cd6841d61d151f17cfaae37c1", name="asm-diskc", owner="grid", group="asmadmin", mode="0660"
kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c29981370abb4b6dbf6101ad8e9f", name="asm-diskd", owner="grid", group="asmadmin", mode="0660"
kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c29b71c709b99b63547534028558", name="asm-diske", owner="grid", group="asmadmin", mode="0660"

kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c2942fbfb7d286d52d2e7fa5cf05", name="asm-diskg", owner="grid", group="asmadmin", mode="0660"
kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c29ac6f46745dccdcb2e623064da", name="asm-diskh", owner="grid", group="asmadmin", mode="0660"
[root@rac01 ~]#

 

编写/etc/udev/rules文件,添加asm块设备

将生成的内容保存在99-oracle-asmdevices.rules文件中。

修改磁盘名,便于识别：asm-grid1……

vim /etc/udev/rules.d/99-oracle-asmdevices.rules

linux 6.x

#linux 6.x
kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c29cd6841d61d151f17cfaae37c1", name="asm-grid1", owner="grid", group="asmadmin", mode="0660"

kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c29981370abb4b6dbf6101ad8e9f", name="asm-grid2", owner="grid", group="asmadmin", mode="0660"

kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c29b71c709b99b63547534028558", name="asm-dgsystem", owner="grid", group="asmadmin", mode="0660"

kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c29bbaf58c22dcb92b6f6e4c67e9", name="asm-dgrecovery", owner="grid", group="asmadmin", mode="0660"

kernel=="sd*", bus=="scsi", program=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", result=="36000c29ac6f46745dccdcb2e623064da", name="asm-dgdata2", owner="grid", group="asmadmin", mode="0660"

 

linux7.x

#linux 7.x

5、重启udev设备

/sbin/udevadm control --reload-rules

/sbin/start_udev

udevadm trigger

systemctl restartsystemd-udevd.service

[root@rac01 ~]# partprobe

[root@rac01 ~]# ll /dev/a*

crw-rw----. 1 root video 10, 175 9月   4 02:47 /dev/agpgart

lrwxrwxrwx. 1 root root        3 9月   4 02:59 /dev/asm-dgdata1 -> sdg

lrwxrwxrwx. 1 root root        3 9月   4 02:59 /dev/asm-dgdata2 -> sdh

lrwxrwxrwx. 1 root root        3 9月   4 02:59 /dev/asm-dgrecovery -> sdf

lrwxrwxrwx. 1 root root        3 9月   4 02:59 /dev/asm-dgsystem -> sde

lrwxrwxrwx. 1 root root        3 9月   4 02:59 /dev/asm-grid1 -> sdc

crw-------. 1 root root  10, 235 9月   4 02:47 /dev/autofs

[root@rac01 ~]#

 

6、重新生成

# rm -rf /dev/asm-dgsystem 

/sbin/udevadm control --reload-rules

/sbin/start_udev

udevadm trigger

systemctl restartsystemd-udevd.service

ll /dev/a*

 

***************************************************************************************

restartudev service

restart the udev service.

# #ol5
# /sbin/udevcontrol reload_rules
 
# #ol6 and ol7
# udevadm control --reload-rules
 
# #ol5 and ol6 : not needed for ol7
