Review the following requirements and considerations for SafeMode:
-
From firmware version 5.3.7 and later, Pure Storage has introduced an option called SafeMode snapshots. Commvault supports SafeMode snapshots. However, starting from version 5.6.16 to 6.3.3, array-wide safe mode is not supported. Additionally, it’s important not to enable safe mode configuration on Commvault created protection groups.
-
From firmware version 6.3.4 and later, SafeMode is supported. The following will be considered for Commvault created protection groups:
-
When there is a target removal (change in the source array to target array mapping at the copy level), a new protection group will be created.
-
When the Commvault created protection group is ratcheted externally or array-wide SafeMode is enabled, if a volume is removed from subclient content, a new protection group will be created as the default value of the snapshot configuration Behavior of SafeMode protection groups if subclient content is removed is Create a new protection group.
-
When the Commvault created protection group is ratcheted externally or array-wide SafeMode is enabled, if a volume is removed from subclient content, same protection group will be used if the snapshot configuration Behavior of SafeMode protection groups if subclient content is removed value is set to Use existing protection group.
All volumes in the protection group will be snapped even though they are not part of the snapshot backup.
