A
The shared logical volumes and filesystems did not have database permissions.
B
There was a test instance running on the standby system that must be shutdown.
C
The tablespaces had an indicator indicating that the database had not shutdown properly.
D
The startup script for the highly available instance did not first perform cleanup operations.

The pSeries technical specialist is designing a two LPAR p5-570 with eight total processors. The system is a test system to run AIX 5.2. The customer has stated a preference for internal disks for the boot devices. The customer has said they may later need to run three or four LPARs without increasing the number of processors. What should the pSeries technical specialist tell the customer about the ability of the p5-570 to meet their requirements？（）A、It will require additional SCSI adapters and I/O drawers or external disks to support more than two LPARs.B、It has sufficient built-in SCSI controllers and disk enclosures to support four total LPARs by only adding the necessary additional disks.C、It is unable to use internal disks for LPARs and therefore additional adapters I/O drawers or external disks must be used to support all LPARs.D、It can support six LPARs with internal disks but will require special features， cables and an adapter to support the additional LPARs with internal disks.
