Commands for checking back-end configuration
Several ONTAP commands provide information about the storage array configuration, including back-end configuration errors. These commands are particularly useful during installation verification and troubleshooting.
The storage array config show
command is the first command to use during installation verification. It is also the first command to use if you notice that your system is not working as you expect, or if you receive an error message.
Commands that are particularly useful for installation verification and troubleshooting are shown in the following table:
Command | Description | ||
---|---|---|---|
|
Provides information, at the storage array level, about the configuration of the back-end devices in a deployment with ONTAP systems using array LUNs. This command shows how storage arrays connect to the cluster. If ONTAP detects an issue that would prevent the ONTAP systems using array LUNs and storage arrays from operating properly together, This command is also useful for verifying that the configuration is set up as you intended. For example, you can look at the output to confirm that the number of array LUN groups that you intended were created. |
||
|
Displays information about all storage arrays visible to the cluster or about the storage array that you specify. If the number of array LUNs presented exceeds the capacity of the system, the Error text field shows you the number of LUNs that ONTAP could not discover. You should watch for this issue on low memory systems in particular. |
