I am getting ready to update all our WAE's to 4.1.1c. This is the third update and I am getting concerned about disk space on all the devices. However, I can not seem to locate the .bin files on the disks and/or how to manage these files. Reading the config guides has been no help. Can anyone provide some guidance?
Thanks in advance.
WAAS is not an IOS router. The .bin image file on a router is stored as a .bin and only extracted on boot. That is not the case with WAAS.
With WAAS, when you install the .bin image, it is uncompressed and the various software components are installed throughout the system. Some of it goes in the flash. Some of it goes on the disk. Some of it on the disk is not fully installed until you reload the WAE. Then, on boot, there is no effort to uncompress the original .bin because it was already uncompressed and installed all over the system.
Also, the flash is not in a file system format where you can just get a directory listing.
Copies of last installed files are kept on the system, and you can use a "restore rollback" to the previous version. If you want to know what that version would be, you can use "show version last".
