Drive Paths pane

This pane shows path information for drives. This pane appears only if a drive is configured as a shared drive or if multiple paths to a drive are configured.

Table: Drive paths pane describes the columns in this pane. Review the Note column for any restrictions.

Table: Drive paths pane

Column

Description

Drive Name

Contains the configured name of the drive.

Device Host

The name of the device host that has the drive.

NDMP Host

If NDMP-attached, contains the name of the NDMP control host. (Requires an NDMP license.)

Control

Control mode for the drive can be any of the following:

  • robot_designation (Applies only to robotic drives)

    For example, TLD.

    The robotic daemon that manages the drive that is connected to ltid (the device daemon and Device Manager service). The daemon is running. The drive is in the usable state. AVR is assumed to be active for the drive, as all robotic drives must be in AVR mode (not OPR mode).

  • DOWN-robot_designation (Applies only to robotic drives)

    For example, DOWN-TLD.

    The drive is in an unusable state because of the following:

    It was downed by an operator or by NetBackup.

    When the drive was configured, it was added as a down drive.

  • DOWN (Applies only to standalone drives)

    In this mode, the drive is not available to Media Manager.

    A drive can be in a DOWN mode because of problems or because a user set it to that mode by using Actions > Down Drive.

  • PEND-robot_designation (Applies only to robotic drives)

    For example, PEND-TLD.

  • PEND (Applies only to standalone drives)

    If the drive reports a SCSI RESERVATION CONFLICT status, this column shows PEND. This status means that the drive is reserved when it should not be reserved.

    Some server operating systems (Windows and HP-UX) may report PEND if the drive reports Busy when opened. You can use the AVRD_PEND_DELAY entry in the Media Manager configuration file to filter out these reports.

  • AVR (Applies only to robotic drives)

    The drive is in a usable state. Automatic volume recognition is enabled, but the robotic daemon that manages the drive is not connected or is not functional. Media mounts do not occur automatically, but an operator can insert a tape in the drive. Alternatively, you can use the robtest utility to force a tape mount.

  • AVR (Applies only to standalone drives)

    The drive is running with automatic volume recognition enabled.

  • OPR (Applies only to standalone drives)

    The drive is running in OPR mode.

    In NetBackup 6.0, OPR mode is functionally equivalent to AVR mode for automatic drive assignment. Drive paths in OPR mode can be assigned if they satisfy the mount request.

  • SCAN (Applies only to NetBackup Enterprise Server.)

    A drive is configured for Shared Storage Option but has no available scan host. To be considered available, a host must have an SSO_SCAN_ABILITY factor of non-zero and have the drive in the UP state.

    SCAN can be caused if all available scan hosts have the drive in the DOWN state. Other hosts (that are not scan hosts) may want to use the drive, but have a scan factor of zero. The drive is unusable by NetBackup until a scan host is assigned.

  • <Mixed> (Applies only to NetBackup Enterprise Server.)

    The control mode for a shared drive may not be the same on all hosts that share the drive. For shared drives, each host can have a different status for the drive. The status of individual paths to the drive appears in the Drive Path column. If the control modes are all the same, that mode appears.

Cluster Name

For a Virtual Cluster, displays the cluster name. (Applies only to supported cluster environments.)

Additional information is available.

See the NetBackup High Availability Administrator's Guide.

Drive Path

For a UNIX device host or an NDMP-attached path on an NDMP host, this column contains the drive path.

Port

For a Windows device host, this column contains the SCSI port number of the drive.

Bus

For a Windows device host, this column contains the SCSI bus number of the drive

Target

For a Windows device host, this column contains the SCSI target number (or SCSI ID) of the drive

LUN

For a Windows device host, this column contains the SCSI logical unit number of the drive

NDMP Host

Contains the name of the NDMP control host. (Requires an NDMP license.)

If multiple drive paths are configured, this column contains Multiple.\

If the drive is configured as a shared drive (Shared Storage Option), this column contains Multiple. (Applies only to NetBackup Enterprise Server.)

Drive Index

The drive index that was assigned during configuration.
