The bootinfo command does not have a man page, can I use it?
The command /usr/sbin/bootinfo has traditionally been used to find out information regarding system boot devices, kernel versions, and disk sizes. This command has been deprecated in favor of the command /usr/bin/getconf.
The bootinfo man page has been removed, and the command is only used in AIX by the booting and software installation utilities. It should not be used in customer-created shell scripts or run by hand.
The getconf command will report much of the same information that bootinfo will:
What was the device the system was last booted from?
$ getconf BOOT_DEVICE
What size is a particular disk in the system?
$ getconf DISK_SIZE /dev/hdisk0
What partition size is being used on a disk in the system?
$ getconf DISK_PARTITION /dev/hdisk0
Is the machine capable of running a 64-bit kernel?
$ getconf HARDWARE_BITMODE
Is the system currently running a 64-bit or 32-bit kernel?
$ getconf KERNEL_BITMODE
How much real memory does the system have?
$ getconf REAL_MEMORY
