A customer wants to change a production RAID Group from RAID 5 (7D+1P) to RAID 6 (6D + 2P) on a VSP G700 during normal operations. They have just unmapped the LUNs from the channel ports. What needs to be performed next?
Technical Justification for Correct Answer: DCorrect Answer: D - The RAID Group must be deletedWhy D is the best option: On a Hitachi VSP G700, changing the RAID level of an existing production RAID Group from RAID 5 to RAID 6 during normal operations, after unmapping the LUNs from the channel ports, requires the RAID Group to be deleted and then recreated with the desired new RAID configuration. This is because the storage system does not support direct, online modifications to the RAID level of an existing RAID Group. Deleting the RAID Group allows for the reconstruction of the group with the new RAID 6 (6D + 2P) configuration, ensuring data integrity and system stability.Why Other Options are Less Suitable:A: The RAID level must be changed in Storage Navigator: This option is incorrect because Storage Navigator, while a comprehensive management tool, does not support online RAID level changes for existing RAID Groups on a VSP G700. Such a capability would pose significant risks to data integrity without a structured process like deletion and recreation.B: The RAID level must be changed in the SVP Maintenance window: Although the SVP (Storage Virtualization Platform) Maintenance window is used for various low-level operations, online RAID level changes for production RAID Groups are not supported through this interface either, making this option invalid for the described scenario.C: The RAID 5 Group must be put into DRU (Direct Read Vulnerability) mode in Storage Navigator: Placing a RAID Group in DRU mode is related to handling failed disks or preparing for maintenance to prevent data loss, not for changing the RAID level. This mode does not facilitate RAID configuration changes and is unrelated to the customer's requirement.

q. 289 - the correct answer should be b not d, since the question asks for the most secure way to provide access to a s3 bucket (a single one), and by principle of the least privilege you should not be giving access to all buckets.
