new disk on server
Back to the well for this ASM neophyte.
Oracle Linux 5.6 64bit
Oracle db 11.2.0.1
oracle asm 11.2.0.2
This from my SA

We previously had 2 x 160 GB SSD drives, I’ll call them Original1 and Original2. When the server booted it assigned the device names in the order it found the drives, so it assigned them
Original1 /dev/fioa
Original2 /dev/fiob
There was one empty slot in the box for another SSD drive, which is where I installed the new one, which I’ll call New1. However, this slot is detected before the others on booting, so now when the server comes up, the devices are assigned as follows:
New1 /dev/fioa
Original1 /dev/fiob
Original2 /dev/fioc
So I think ASM is expecting fioa and fiob to have your data on them, when in fact fioa is the new, empty drive, and fiob is the disk that used to be called fioa, so the data it expects on that one is not correct either. fioc is the one that used to be called fiob, but ASM doesn’t look for an fioc, so it’s not even seeing that one.
My thought was that if you could go into ASM (prior to starting the database) and reassign the names so that ASM would look for fiob and fioc in place of fioa and fiob, then we could leave things as they are. If not, then I will open the server back up, and remove all three SSD drives and rearrange them so that
Original1 goes in the slot where New1 is now, and gets /dev/fioa assigned on boot
Original2 goes in the slot wher Original1 is now, and gets /dev/fiob assigned on boot
New1 goes in the slot wher Original2 is now, and gets /dev/fioc assigned on boot.
