Block size is 32768 bytes not 131072 bytes. Verify the device configuration

Question

Hi Guys,

we are running NetWorker 7.4.1 on a Solaris platform. We have a Unix storage node with a M2500 with 6 sdlt320 tape drives attached to it.

Now 5 tape drives are working as they should, whilst 1 of them is marking tapes full prematurely with this error following:

Block size is 32768 bytes not 131072 bytes. Verify the device configuration

I am not really a Unix person so what is the best way to approach block size issues for the tape drives? I would assume that the driver used for that drive is the same as all the others, how can I check?

Is there a variable that can be set at OS level for 1 particular drive?

Any help is appreciated.

thanks

What is says is that it is getting a block size of 32 kb whereas it is lloking for 128 kb. The variable that can be set is NSR_DEV_BLOCK_SIZE_SDLT=128k but this would work for all the drives and not one in particular.
