the person who backups our pbx (definity g3r)reported that the last time they tried to they got the message - mss currently in use.. F.Y.I. we have a duplicated spe i did a status spe and it shows mode- standby,r-media-out of service,disk-out of service on SPE-A.does this simply means our disk is bad or is their more to it if so what tests can i run which doesnt require me going out of service ?
