Using Udev on Linux 6 to address ASM storage device issues

1. Add record to/etc/scsi_id.config

echo "options=--whitelisted--replace-whitespace" >>/etc/scsi_id.config

2. In this example, the block device sdb-> SDD needs to be bound

[[email protected] ~]# for i in B c D;

> Do

> echo "kernel==\" sd*\ ", bus==\" scsi\ ", program==\"/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/ \ $name \ ", result==\" '/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/sd$i ' \ ", name=\" asm-disk$i\ ", Owner=\ "grid\", group=\ "asmadmin\", mode=\ "0660\" "

> Done

kernel== "sd*", bus== "scsi", program== "/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/$name", RESULT= = "291bbf9b896a0f503", name= "ASM-DISKB", owner= "grid", group= "Asmadmin", mode= "0660"

kernel== "sd*", bus== "scsi", program== "/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/$name", RESULT= = "24D3963EC66158AAC", name= "ASM-DISKC", owner= "grid", group= "Asmadmin", mode= "0660"

kernel== "sd*", bus== "scsi", program== "/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/$name", RESULT= = "2A188DF0F367EC9AD", name= "ASM-DISKD", owner= "grid", group= "Asmadmin", mode= "0660"

3. Write these rule to/etc/udev/rules.d/99-oracle-asmdevices.rules and modify the value of name as needed.

[Email protected] rules.d]# VI 99-oracle-asmdevices.rules

kernel== "sd*", bus== "scsi", program== "/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/$name", RESULT= = "291bbf9b896a0f503", name= "Asm-data", owner= "grid", group= "Asmadmin", mode= "0660"

kernel== "sd*", bus== "scsi", program== "/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/$name", RESULT= = "24D3963EC66158AAC", name= "ASM-OCR", owner= "grid", group= "Asmadmin", mode= "0660"

kernel== "sd*", bus== "scsi", program== "/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/$name", RESULT= = "2A188DF0F367EC9AD", name= "Asm-fra", owner= "grid", group= "Asmadmin", mode= "0660"

4. Start Udev

[Email protected] rules.d]#/sbin/start_udev

Starting udev: [OK]

[Email protected] rules.d]# ll/dev/asm*

BRW-RW----1 Grid asmadmin 8, June 22:43/dev/asm-data

BRW-RW----1 Grid asmadmin 8, June 22:43/dev/asm-fra

BRW-RW----1 Grid asmadmin 8, June 22:43/DEV/ASM-OCR

[Email protected] rules.d]#

Note: RHEL5 commands differ from RHEL6

The RHEL5 command is:/sbin/scsi_id-g-u-s

For example:

For i in B c D;
Do
echo "kernel==\" sd*\ ", bus==\" scsi\ ", program==\"/sbin/scsi_id-g-u-s%p\ ", result==\" ' scsi_id-g-u-s/block/sd$i ' \ ", Name=\ "Asm-disk$i\", owner=\ "grid\", group=\ "asmadmin\", mode=\ "0660\" "
Done
