Hi，when the system is restarted, the storage lun drive letter is

/dev/sda

, and after the restart, it becomes

/dev/sdc

or other.

We tried to use the Udev strategy to create the

58-storage.rule

rule to solve this problem, but when the system restarts, it prompts that the udev version does not support renaming kernel device nodes, such as

"NAME=/sda%n ignored, kernel device nodes can not be renamed; please fix it in /etc/udev/rules.d/10-test.rules:2"

. We want to fix the drive letter under

/dev/sda

, so how do we solve this problem?

Among them, the linux version number is

Linux nas 3.10.0-693.el7.x86_64

, and the query result of using the

rpm -qa | grep udev

command is

libgudev1-219-42.el7_4.1.x86_64

python-pyudev-0.15- 9.el7.noarch

, and the rules information is as follows:

[root@RHEL7X rules.d]# cat 58-storage.rule
SUBSYSTEMS=="scsi",SUBSYSTEM=="block",KERNELS=="2:0:0:1",NAME="/sda%n"

Thank you advance for sharing your experience here.
