Final answer:
To identify logical partitions on a SCSI hard drive, the fdisk command should be used. It is a disk partitioning tool that allows for the management of partition tables.
Step-by-step explanation:
The correct way to identify logical partitions on a SCSI hard drive would be using the fdisk command. The fdisk utility is a disk partitioning tool that is commonly used in Unix and Unix-like operating systems to view, create, resize, delete, and manipulate partition tables on hard disk drives.
It is especially useful for managing traditional BIOS-based systems, and for drives that are not using GUID Partition Table (GPT) which is more common for modern Unified Extensible Firmware Interface (UEFI) systems.
The format command is typically used to format a drive with a file system, while the mount command is used to mount a file system to a directory structure. The mkfs command is similar to format, as it is used to create a file system on a partition or logical volume.
