Operating Systems AIX How to remove a device in use?

Looks like a mess to me.
dac's and tapes on fcs/fscsi1!
Never mix disk and tape / dac storage on the same adapter.
dac3 seems to be the problem but there is still a path to something like a dar under it.
If you can get to the box and rootvg is on local disks then pull the fibre and reboot, then rmdev away.
Re-plug the fibre and then cfgmgr or reboot - split the disks and tape though.....

NAME
cfgmgr - Configuration management server SYNOPSIS
/sbin/cfgmgr DESCRIPTION
The cfgmgr configuration management server works with the kernel load server (kloadsrv) daemon to manage the subsystems that are dynami- cally configurable, loadable, or both. The cfgmgr server starts up automatically when a client (such as the sysconfig command) makes a con- figuration management request. Examples of configuration management requests are requests to configure, reconfigure, query, or unconfig- ure a subsystem. The cfgmgr server allows query operations from any superuser (root login), local or remote. The superuser on the local system is also allowed to configure, reconfigure, or unconfigure local kernel subsystems. Remote access to the kernel subsystem configuration is allowed through the /etc/cfgmgr.auth file. System administrators working on hosts listed in that file can also configure, reconfigure, or uncon- figure local kernel subsystems. If the /etc/cfgmgr.auth file does not exist or is empty, no remote users are allowed to configure, recon- figure, or unconfigure local kernel subsystems. If you use the sysconfig -v command, the cfgmgr server displays debugging information to the /dev/console screen. See the sysconfig(8) ref- erence page for more information about the -v flag.
