When you save storage allocations to a blade, consider the following:
The storage allocations saved in Oracle ILOM are based on the hardware currently installed in the chassis (SAS-2 NEMs or storage blades). Changes in the chassis hardware configuration can result in a loss of a storage blade group. Therefore, you should back up all chassis storage allocations in Oracle ILOM. For more information, see Backing Up and Recovering SAS-2 Zoning Assignments.
The Sun Blade Zone Manager dialog (Modify Group or New Assignments) must remain open during the entire Save operation. If the Sun Blade Zone Manager dialog is closed while the Save operation is in progress, only a portion of the storage blade group will be preserved.
Do not remove or power cycle any of the chassis hardware components that are part of a storage blade group while a Save operation is in progress. Doing so will cause the group allocation not to save properly.
