To enable or disable SnapShot Data with rebooting
NOTE: If you enable/disable SnapShot because of a spin-down instruction
when Power Saving, the spin down may fail if the instruction is received
immediately after the array restarts. If 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 disabling or enabling
SnapShot.
1. To enable SnapShop using CLI, from the command prompt, register the
array in which the status of the feature is to be changed, then connect
to the array.
2. Execute the auopt to change the status (enable or disable).
Following is an example of changing the status from enable to disable.
If you want to change the status from disable to enable, enter enable
after the -st option.
•
% auopt -unit array-name -option SNAPSHOT -st disable
Are you sure you want to disable the option? (y/n[n]): y
The option has been set successfully.
In order to complete the setting, it is necessary to
reconfigure memory or reboot the array.
Are you sure you want to start reconfigure memory? (y/n [n]): n
Host will be unable to access the array while restarting. Host
applications that use the array will terminate abnormally.
Please stop host access before you restart the array.
Also, if you are logging in, the login status will be canceled
when restarting begins.
When using Remote Replication, restarting the remote array
will cause both R
emote Replication paths to fail.
Remote Replication pair status will be changed to
"Failure(PSUE)" when pair status is "Paired(PAIR)" or
"Synchronizing(COPY)". Please change Remote Replication
pair status to "Split(PSUS)" before restart.
Do you agree with restarting? (y/n [n]): y
Are you sure you want to execute?
(y/n [n]): y

It may take time for the array to respond, depending on the condition of
the array. If it does not respond after 25 minutes, check the condition of
the array.
3. Execute auopt to confirm whether the status has been changed. For
