Affected NV Version: 7.4.x
OS Version: Linux
When a standalone tape device is locally attached to a machine running Red Hat Enterprise Linux 4,Update 1 (RHEL4U1), the device may not be recognizable to the NetVault Server. With this version ofRHEL, the SG driver used to support this form of device is not automatically loaded, and must be manually loaded on the RHEL4U1 system.
In order to support these devices, after manual load of the driver it is necessary to stop and restart NetVault Services on the NetVault Server. This issue only occurs in instances in which the RHEL4U1 machine does not also have some form of library/changer device locally attached (i.e., the standalone device is the only type of backup device locally attached to the RHEL4U1 machine). The Linux “SG” driver is an upper level SCSI subsystem device driver that is used primarily to handle devices such as a standalone tape drive. For complete details on obtaining and loading this driver, please see the relevant RHEL4U1 documentation.
