Re: SC10 disk problem

The problem is probably caused by the disk.
The EMS shows disk device 0/7/0/0.0.0. This is the disk in the first slot (#0), but if the device is configured to split bus and low addressing, the slot #1 gets also SCSI ID 0 (different bus). You can check this with ioscan and have a look at the dip switch settings on the rear.

Hope this helps!

Torsten.

Re: SC10 disk problem

The host detected a SCSI bus hang and performed a Bus Reset to recover from the situation.

You might want to check the FW revisions on your Disk drives connected to the particular SCSI HBA and upgrade the Disk FW if they aren't current.
