Re: [Networker] Read Open Errors on LTO Drives in L180

Yes, it is SCSI and we have applied the st patch.  The I/O error happens on
media that has already been labeled and written to by Legato.  I have
attached the portion of the messages file.

Thanks for your help!

Hi Scott,

Do you have the latest st patch (108725-09).  There are some references to
Seagate LTO in version 8 of the patch.

Is this via SCSI or FC? If FC, are the drives part of a fabric? zoned to
multiple hosts?

It is normal for unlabled/new tapes to report a read error when they are
trying
to be mounted since a NW label doesn't yet exist on the volume.

Also, you forgot to include your /var/adm/messages.

Regards,
        /\/elson
