Un-installing

To uninstall TCE, the key code provided for optional features is required.
Prerequisites for uninstalling
• TCE pairs must be released (the status of all LUs must be Simplex).
• The remote path must be released.
• Data pools must be deleted, unless a SnapShot system exists on the
array.
• Make sure a spin-down operation is not in progress.
To uninstall TCE without rebooting
1. From the command prompt, register the array in which the TCE is to be
uninstalled, and then connect to the array.
2. Execute the auopt command to uninstall TCE. For example:
•
% auopt -unit array-name -lock on -keycode manual-attached-keycode
Are you sure you want to lock the option? (y/n [n]): y
The option is locked.
In order to complete the setting, it is necessary to reconfigure memory or
reboot the subsystem.
Are you sure you want to start reconfigure memory? (y/n [n]): y
While in progress, performance degradation of host I/Os to the array will
occur.
Are you sure you want to continue? (y/n [n]): y
Memory reconfiguring started successfully.

3. Execute the auopt command to confirm that TCE is uninstalled. For
example:
•
% auopt –unit array-name –refer
DMEC002015: No information displayed.

Uninstalling TCE is now complete
To uninstall TCE with rebooting
NOTE: If you uninstalling TCE during a spin-down instruction when Power
Saving, the spin down may fail if the instruction is received immediately
after the array restarts. When the spin-down fails, perform the spin-down
again. Check that the spin-down instruction has not been issued or has
been completed (no RAID group in the Power Saving Status of
Normal(Command Monitoring) exists) before uninstalling TCE.
1. From the command prompt, register the array in which the TCE is to be
uninstalled, and then connect to the array.
