as well as the following in the cfgadm -alv output, and notice that the disk does not have a relevant dsk/c# t# d#.

The cfgadm and format command will not work with above disk device. The platform log indicate that there is a hot removal and insertion of disk replacement.

The devfsadm command should be used with the options "-c disk -Cv" to clean up and device path. Upon successful relinking of the device path customer and/or field engineer should be able to cfgadm and bring the disk back to OS control.

If the devfsadm option was not successful you will need to reboot the platform or engage OS/disk driver expert engineer.
