The problem that the UUID cannot be returned when rac asm udev is installed on the VM

The problem that the UUID cannot be returned when rac asm udev is installed on the VM

Use UDEV service to solve the rac asm storage device name
1. Confirm that necessary UDEV packages have been installed on all RAC nodes.

[Root @ rh2 ~] # Rpm-qa | grep udev
Udev-095-14.21.el5

2. Obtain the unique identification name of the block device through scsi_id. Assume that the LUN sdc-sdp already exists on the system.

For I in c d e f g h I j k l m n o p;
Do
Echo "sd $ I" "'scsi _ id-g-u-s/block/sd $ I '";
Done3
For I in B c d e f g h I j k; doecho "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

Done

No return value. UDEVTEST is used to check whether the ID cannot be returned.

Solution

The first device cannot be formatted

Add disk. EnableUUID = "TRUE" to the vmx file of the VM"
If you configure any other virtual machine, such as adding a disk, modifying the NIC type, or performing other operations,
The disk. EnableUUID parameter is reset to FALSE again. Therefore, you must manually modify this parameter after each virtual machine setting.

To avoid manual modification
You can only use udevinfo to obtain SYSFS [start] And SYSFS [size ].

Udevinfo-a-p/sys/block/sdb/sdb1

KERNEL = "sdb1", SUBSYSTEM = "block", SYSFS {size} = "16771797", SYSFS {start} = "63", NAME = "asmdisk1-crs ", OWNER = "grid", GROUP = "asmadmin", MODE = "0660"

If it is VBOX, we recommend that you change the hard disk bus to SATA

For LINUX 5 formatted, use ASMLIB
