[rescue] DLT drive dead want to replace without rebooting

[Brian Deloria]

Hello,

  I've got a DLT drive that bit the dust, and I've been doing some research
here and I'd like to hotswap the drive with it's replacement when it gets
here, however I'm not sure how nor do I know if I can reset the scsi bus.
The tape drive is on it's own controller which is the first good thing.

  I'm reluctant to reboot the machine for one simple reason my predecessor
suspected that the NVRAM had gone bad, it's been online for over 600 days,
and if the NVRAM gets replaced then there's several software licesnses that
are bound to the hostid which would cause a great deal of grief.

If you have any suggestions please let me know.

Thanks,

Brian
