問題文
One storage server has to be powered down for maintenance while the databases of the cluster keep running. Which command sequence follows the documented procedure?
選択肢
- Drop the grid disks of the cell from their disk groups, which starts a rebalance so the data leaves the cell before the services of the cell are stopped by the administrator.
- Stop the cell services with the shutdown command for all services, which checks the redundancy of the disk groups of the cluster first and takes the grid disks offline in Oracle ASM before the services stop.
- Dismount the disk groups from every Oracle ASM instance of the cluster, which releases the grid disks of that cell so the services of the cell can be stopped from the operating system.
- Power the cell off from the service processor, which lets Oracle ASM notice the loss and start the repair timer so that the disks are dropped when the timer has run out.
