sda sdb sdc drives not consistent
My company has a disk enclosers for 10 disks that can be used for RAID.
I am doing an experiment where i have only 3 disks in the slots.
After booting the linux machine and load the driver (for RAID pci card), I can see those 3 disks-- sda, sdb, and sdc-- using "fdisk -l"
I took sdb drive out of the tower, then call "fdisk -l".
Now I see only sda and sdc as expected.
Then i put the sdb back to the same slot and call "fdisk -l"
Now I see sda, sdc, and sdd.
Is this how it is supposed to work, or it is a bug of the RAID pci driver?
