Getting error on a drive

Hello All,

I am getting below error message for a drive in /var/adm/messages

Feb 12 07:12:07 p02danbs03 avrd[23319]: [ID 229023 daemon.notice] Reservation Conflict status from OC9940B_a1p02d14 (device 6)

Kindly suggest as backups are getting failed on this drive randomly with error 84.
