Configuration cautions
Observe the following cautions:
In multiple-initiator (multiple host bus adapter) environments, NetBackup uses SCSI reservation to avoid tape drive usage conflicts and possible data loss problems. SCSI reservation operates at the SCSI target level; the hardware that bridges Fibre Channel to SCSI must work correctly.
By default, NetBackup uses SPC-2 SCSI reserve and release. Alternatively, you can use SCSI persistent reserve or disable SCSI reservation entirely.
For information about the NetBackup use of SCSI reservation, see the following:
"Enable SCSI reserve" in the NetBackup Web UI Administrator's Guide, Volume I.
"How NetBackup reserves drives" in the NetBackup Web UI Administrator's Guide, Volume II.
Cohesity does not recommend or support the use of single-ended to differential SCSI converters on NetBackup controlled devices. You may encounter problems if you use these converters.
