To familiarize yourself with using USB drives on AIX, take a look at the following article at IBM developerWorks:
http://www.ibm.com/developerworks/aix/library/au-flashdrive/
Before you start using it, make sure you DLPAR the USB controller to your LPAR, if not done so already. You should see the USB devices on your system:
# lsconf | grep usb
+ usbhc0 U78C0.001.DBJX589-P2 USB Host Controller
+ usbhc1 U78C0.001.DBJX589-P2 USB Host Controller
+ usbhc2 U78C0.001.DBJX589-P2 USB Enhanced Host Controller
+ usbms0 U78C0.001.DBJX589-P2-C8-T5-L1 USB Mass Storage
After you plug in the USB drive, run cfgmgr to discover the drive, or if you don't want the run the whole cfgmgr, run:
# /etc/methods/cfgusb -l usb0
Some devices may not be recognized by AIX, and may require you to run the lquerypv command:
# lquerypv -h /dev/usbms0
To create a 2 TB file system on the drive, run:
# mkfs -olog=INLINE,ea=v2 -s2000G -Vjfs2 /dev/usbms0
To mount the file system, run:
# mount -o log=INLINE /dev/usbms0 /usbmnt
Then enjoy using a 2 TB file system:
# df -g /usbmnt
Filesystem GB blocks Free %Used Iused %Iused Mounted on
/dev/usbms0 2000.00 1986.27 1% 3182 1% /usbmnt
