Why each option
AIX reserves fixed logical volume names for system components created in rootvg during installation. hd6 is the default paging space logical volume created at install time.
hd1 is the logical volume for the /home filesystem, which holds user home directories rather than paging space.
hd5 is the boot logical volume (BLV) that contains the AIX boot image and is not mounted as a filesystem - it is not the paging space.
hd6 is the logical volume name assigned to the default paging space created in the rootvg volume group during AIX installation, providing the system with swap space and residing on the boot disk alongside other rootvg members such as hd4 (root filesystem) and hd5 (boot logical volume).
hd7 is associated with the system dump device in rootvg, used to capture memory during a system crash, and is not designated as the default paging space.

Sunita A.Feb 5, 2026The correct answer is C, hd6. During an AIX installation, the system automatically creates a set of default logical volumes within the rootvg volume group, and each one gets a fixed, well-known name. The paging space logical volume is always named hd6, and that name is hardcoded into the AIX installation process, so you will see it on every default AIX system regardless of hardware or version. A quick mnemonic that helps our study group keep the rootvg defaults straight is "5 boots, 6 swaps, 7 logs" - hd5 is the boot logical volume, hd6 is paging (swap), and hd7 is the system dump device, so knowing those three anchors lets you eliminate distractors fast on exam day.
Nina C.Feb 7, 2026Good mnemonic but just a heads up that "7 logs" tripped me up at first because hd7 is the system dump device and hd8 is actually the JFS log, so I rewrote it as "5 boots, 6 swaps, 7 dumps, 8 logs" to keep myself straight on exam questions that split those two apart.
Ola B.Feb 1, 2026Saw hd6 staring back at me on test day, picked C without blinking.
Nina C.Feb 15, 2026Pretty sure it is D, hd7 is the default AIX paging partition.
Ola B.Feb 17, 2026Nina, it is actually C, hd6 is the default AIX paging (swap) partition, while hd7 is used for the sysdump device. Spin up an AIX lpar or WPAR and run lsvg -l rootvg to see it listed right there.
