Handling Errors when More Than 10 NetBackup Jobs are Active

Using the Configure Storage Devices Wizard with Optical Disk Drives

The Media Manager device configuration wizard can discover and automatically

configure optical disk drives that have a /dev/sctl SCSI passthru device file.

Note Optical disk drives are not supported in an SSO configuration.

▼ To use the device configuration wizard

1. Create the passthru device files.

See “Configuring Device Files for the sctl Passthru Driver” on page 56 for

instructions.

2. Start the wizard from the list of wizards displayed in the right pane of the Media and

Device Management window of the NetBackup Administration Console.

Select Configure Storage Devices.

See theVERITAS NetBackup Media Manager System Administrator’s Guide for UNIX and

Linux or the VERITAS NetBackup Media Manager System Administrator’s Guide for

Windows for more information on using this wizard.

Handling Errors when More Than 10 NetBackup Jobs are

Active

If you have an HP-UX master server and more than 10 NetBackup jobs are active,

additional jobs may fail with NetBackup 81 errors (the Media Manager volume daemon

(vmd) is not active).

This error indicates that the operating system has exceeded the number of processes that

can have undo operations pending on a given semaphore. These errors will continue to

occur until the number of active jobs falls below 10.

In these cases, VERITAS recommends modifying the HP-UX kernel parameters to increase

the value of semmnu by at least the number of desired concurrently active jobs greater

than 10. (The default value for semmnu is 30.)
