Hello All,
I have a virtual machine to which I dynamically attach/detach disk devices. On this VM the boot device is always '/dev/sda'.
When a attach and detach different disk continuously to this virtual machine, every-time, the same device file '/deb/sdb' is created. Is there anyway I can tell udev subsystem to not to reuse the previously used device names?
IMHO that's understandable since the guest think the same disk is reinserted back.
So, the key here is to use your virtual machine somehow to pass information to the guest that this is another disk.
What virtual machine do you use anyway?
Hello Mulyadi, I am using ESX and sometimes I have to attach disks dynamically and remove them. I have caching solution installed on my machine, if I ever cache the attached disk, remove it, and attach a different disk, this newly added disk might accidentally be treated as original disk and might be cached incorrectly. Therefore, I wanted to ensure that every time a disk is attached it is named differently. Thanks and Warm Regards, Prasad
