Solaris Cluster 3.2 and later Software Quorum Feature (Doc ID 1376783.1)

Last updated on FEBRUARY 23, 2017

Applies to:

Solaris Cluster - Version 3.2 U2 to 4.3 [Release 3.2 to 4.3]
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on x86-64 (64-bit)

Goal

This article shows how to add Software Quorum to a Solaris Cluster 3.2 or 3.3 system.
Software Quorum is a new concept introduced in Solaris Cluster 3.2 release.
It allows the cluster administrator to add a Quorum Device, a disk or lun that does not support SCSI 3 reservations properly.
Solaris Cluster uses an exclusive area on the disk that is hidden from users by the target driver.
We normally use this area for PGRe (emulated SCSI3 PGR), but with the implementation of Software Quorum
we can write the keys even if the disk does not support SCSI protocol.


Software Quorum should not to be confused with Quorum Server.
