our SUN people are not very happy on how TSAMP handles Quorum Support. In our case we use network tiebreaker but this isn't a sure method because both sub clusters can still reach the defined gateway IP. Now we are in discussion about using SCSI tiebreaker instead. They want to know which type of SCSI-reservation is supported by the IBM.TieBreaker class? And is it possible to provide more and deeper information on how it works?

Re: SCSI tie breaker on SUN Solaris2011-12-07T10:11:44Z in response to xf00657Hello,
yes, the usage of SCSI-2 reservation applies to all SCSI tie breakers.
In my first reply I forgot to note that there is now an SCSIPR tie breaker available for Linux, which uses SCSI-3 reservation, but this is not available for Solaris. The description did not make it into the SA MP 3.2.2 books, so it is so far only contained within the Release Notes of SA MP 3.2.1 / 3.2.2.
There is also a description how to use SCSI-3 reservation for the AIX 'DISK' tie breaker within the Relase Notes.
