sure you can :

nac5> storage disable usage: disable adapter <name> disables and stops I/O traffic on adapters and switches nac5> storage enable usage: enable adapter <name> enables and starts or restarts I/O traffic on an adapter

use this with the id of the adapter and you can reset the scsi w/out reboot the filer (great improvment on last dot)

Hi all,

I have a pair of clustered 820's running Data ONTAP 6.4. One of the heads has a SCSI host adapter (Qlogic ISP 1040B) connected to a tape library that we use for backing up the filers. Occasionally the library will become confused and we will need to reset the SCSI interface in order to get it back into an operational mode. In the past we have done a takeover on the partner and then shut down / restarted the head with the SCSI card. Needless to say this is problematic.

Is there any way to reset the SCSI interface on these cards without impacting the filer's operations? If not, are there other replacement cards which would allow me to do this?

Thanks!
