8-10 slot 4mm library for Sun

8-10 slot 4mm library for Sun

Post by Eric Headl » Tue, 27 Nov 2001 23:09:13

I am looking for a  8-10 slot DDS4 tape changer to conect to a Sun
Enterprise 2.  Does anyone have any suggestions as to what I can use ?

1. 4mm tape drive attach to A Sun SparcStation-10

We have A Sun SparcStation-10 (In fact it is aAxil311) with 4mm tape drive
attach to it. The problem is that dumps taks forever on this system. Trying to
dump 550 MBytes of local data (from disk attached to this system too) to the
4mm tape taks almos six (!!!) houres.

The command I am using is:

        /etc/dump 0fusb /dev/rst1 540000 8192b /dev/rsd1h

I tried several blocks size from 20b to 8192b and there is no real improvment
in the dump time.

Thanks in advance,
