Solution

The actual fix is available on oakcli 2.6 version, Hence customers are advised to upgrade to oakcli and run the below

1) stop oakd (oakcli stop oak)
2) remove the disk. if there is any io, asm will detect the io error and start offline/drop the disk. (Check in asm alert log)
3) start oakd, oakd will detect the empty slot and doing nothing (oakcli start oak)
4) re-insert the disk back into the slot, oakd will treat it as new disk and then do all the needy to create the partitions, etc.
5) oakd will generate the proper sql to asm to add the disks back to asm. if the disks were not dropped by asm yet, asm would drop force before the add.
