G System Deinstallation
WARNING! Deinstallation destroys all user data. There is no recovery. This is not the procedure
for regular relocation services (for when the user data is to be saved).
NOTE: If you are planning to reinstall and use the existing license, record the existing license
before performing the uninstall by using the showlicense and showlicense -raw commands.
Only use this deinstallation procedure in the following conditions:
• To wipe all data and format the drives to prevent access to the old data
• To save time to correct an initial installation that was installed incorrectly and that has no
customer data on it
NOTE: In this case, only complete steps 1 to 11 of “Uninstalling the System” (page 134),
and then begin again with the system installation procedures in order to re-install the storage
system.
Before uninstalling a system:
• Verify with a system administrator that the system is prepared for shutdown.
• Complete the “System Inventory” (page 133).
