Device Busy

Hi,

When I check for the available devices through Command Scripter on Tru64 UNIX,I find the system message, "device busy" on 3 devices.
These devices are not really busy.And due to this, there is a performance degradation on the product.Could anybody help me out >>

regards

Re: Device Busy

I had this problem once before. It ended up that I was using a disk on my SAN that someone else was trying to use at the same time. Just curious if your disks are on a SAN. If they are, check to see if they aren't in use by another system.
