From what I see in the screenshot, you are using 9GB simulated disks. If the SIM has been in use for a while, you may have filled the virtual disk that the simulated disks are stored on.
You can check this by stopping it at the boot menu, entering the systemshell, and running df to see the available space on the /sim filesystem
Please choose one of the following:
(1) Normal Boot.
(2) Boot without /etc/rc.
(3) Change password.
(4) Clean configuration and initialize all disks.
(5) Maintenance mode boot.
(6) Update flash from backup config.
(7) Install new software first.
(8) Reboot node.
(9) Configure Advanced Drive Partitioning.

If your /sim file system is filling up, the default size of the IDE1:1 disk is too small for your simulated disk layout. You can either provision fewer or smaller simulated disks, or you can replace IDE1:1 with a larger disk before the very first power on of a new simulator.
