The command output will not show ad0 (the CompactFlash card) mounted, but instead,
ad1 (the hard disk) has the root file system mounted.
Determine Why CompactFlash Card Did Not Mount
Problem To determine why the CompactFlash card did not get mounted, use the following
command:
user@host> show system boot-messages | match "ad0|ad1"
user@host> show system boot-messages | match "ad0|ad1"
ad0: not attached, missing in Boot List
ad1: 28615MB <FUJITSU MHS2030AT> [58140/16/63] at ata0-slave using BIOSDMA Mounting
root from ufs:/dev/ad1s1a
Solution The command output shows that the CompactFlash card (ad0) was removed from the
boot list.
