The statements that are true about the CellCLI command are:

• It has command-line history . According to 1, you can use the up and down arrow keys to scroll through previous commands that you entered in CellCLI . You can also use Ctrl+R to search for a previous command by entering part of it .
• It can be executed on storage servers . According to 1, you can invoke CellCLI by logging in to the Exadata cell as cellmonitor , celladmin , or root user and typing “cellcli” . Within CellCLI , you can perform various management and monitoring tasks for the cell134.
• It can be executed using the DCLI utility . According to 5, DCLI (distributed CLI) is another utility that can be used to execute scripts and commands across multiple storagecells from a single interface. You can use DCLI to run CellCLI commands on multiple cells at once54.

According to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and Resources, you can find diagnostic messages related to this problem in the alert logs for the ASM instances and the alert logs for the prod database instances. The alert logs for the ASM instances will provide information related to the offline asm disks, while the alert logs for the prod database instances will provide information related to whether the prod database instances are connected to the ASM instance or not.

To drop all celldisks on all the storage servers in an X9M-2 quarter rack, you should use the CELLADMIN account, which has the necessary privileges to perform this task. You can use the CELLCLI command-line interface to drop the celldisks. The best way to do this is by calling CELLCLI on all cells using DCLI (Oracle Database Command Line Interface) which allows you to run commands on multiple servers at once. Alternatively, you can use an administrator-created storage server user with appropriate privileges on celldisk objects by calling CELLCLI on all cells using exadcli. It is not recommended to use the CELLMONITOR account, as it has a more limited set of privileges. It is also important to note that EXACLI is not a valid tool for this task
