2. As good an answer as I have found - after a single google it was the first hit:
PowerVM QuickStart

PowerVM Types

• PowerVM inherits nearly all the APV (Advanced Power Virtualization) concepts from Power 5 based systems. It uses the same VIOS software and options as the previous APV.
• PowerVM is Power 6 specific only in that it enables features available exclusively on Power 6 based systems (ie: Multiple shared processor pools and partition mobility are not available on Power 5 systems.)
• PowerVM (and its APV predecessor) are optional licenses / activation codes that are ordered for a server. Each is licensed by CPU.
• PowerVM, unlike its APV predecessor, comes in several different versions. Each is tiered for price and features. Each of these versions is documented in the table on the right.
• PowerVM activation codes can be checked from the HMC, IVM, or from IBM records at this URL: IBM Capacity on Demand: Activation code. The activation codes on the IBM web site will show up as type "VET" codes.

Express • Only available on limited lower-end P6 systems
• Maximum of 3 LPARs (1 VIOS and 2 VIOC)
• CPU Micro-Partitions with single processor pool
• VIOS/IVM only, no HMC support
• Dedicated I/O resources (in later versions)

Standard • Up to the maximum partitions supported on each server
• Multiple shared processor pools
• IVM or HMC managed

Premium • All options in Standard & Live Partition Mobility

• The VET codes from the IBM activation code web site can be decoded using the following "key":
XXXXXXXXXXXXXXXXXXXXXXXX0000XXXXXX Express
XXXXXXXXXXXXXXXXXXXXXXXX2C00XXXXXX Standard
XXXXXXXXXXXXXXXXXXXXXXXX2C20XXXXXX Enterprise

Thank you for trying to help, I found that info as you did before posting here. I'm asking because I have been asked on interview those two questions and I don't know as answers.

The interviewer told me that you can answer those two questions with two commands, each for one question. But I didn't find those two commands.

Thanks.

fsck_msdos

FSCK_MSDOS(8)						    BSD System Manager's Manual 					     FSCK_MSDOS(8)

NAME

     fsck_msdos -- DOS/Windows (FAT) filesystem consistency checker

SYNOPSIS

     fsck_msdos -p [-f] filesystem ...
     fsck_msdos [-fny] [-x snap-backup] filesystem ...

DESCRIPTION

     The fsck_msdos utility verifies and repairs FAT filesystems (more commonly known as DOS filesystems).

     The first form of fsck_msdos preens the specified filesystems.  It is normally started by fsck(8) run from /etc/rc during automatic reboot,
     when a FAT filesystem is detected.  When preening file systems, fsck_msdos will fix common inconsistencies non-interactively.  If more seri-
     ous problems are found, fsck_msdos does not try to fix them, indicates that it was not successful, and exits.

     The second form of fsck_msdos checks the specified file systems and tries to repair all detected inconsistencies, requesting confirmation
     before making any changes.

     The options are as follows:

     -f 	       This option is ignored by fsck_msdos, and is present only for compatibility with programs that check other file system
		       types for consistency, such as fsck_ffs(8).

     -n 	       Causes fsck_msdos to assume no as the answer to all operator questions, except ``CONTINUE?''.

     -p 	       Preen the specified filesystems.

     -x snap-backup    Use a snapshot with snap-backup as backup to check a read-write mounted filesystem.  Must be used with -n.  See fss(4) for
		       more details.  The point is to check an internally-consistent version of the filesystem to find out if it is damaged; on
		       failure one should unmount the filesystem and repair it.

     -y 	       Causes fsck_msdos to assume yes as the answer to all operator questions.

     fss(4), fsck(8), fsck_ffs(8), mount_msdos(8)

BUGS

     fsck_msdos is still under construction.
