The nbdevquery command line utility is the disk equivalent of bpmedialist for tape. The following are the three operations that nbdevquery performs:
-listdv displays status for disk volumes of imported disk pools. It includes such things as whether the volume is online or offline and the number of current readers (or writers) to the volume.
When used with the -D option, the -listdv command returns a large set of data including the following values that NetBackup uses to determine the available free space within the disk pool:
total_capacity : xxxxxxx -- The total size of the disk as derived from the file system.
free_space : xxxxxxx -- The amount of free space on the disk as derived from the file system.
potential_free_space : xxxxxxx -- The total size of all fragments on the disk that have been duplicated as part of a storage lifecycle policy and are eligible for expiration. The potential_free_space value is computed after duplication and expiration sessions. This information is applicable only when capacity managed retention is used for a storage destination.
committed_space : xxxxxxx -- The amount of data that NetBackup estimates as being written to the disk, based on all in-progress backups.
precommitted_space : xxxxxxx -- A helper value for committed_space. This value is decreased as a backup job proceeds and the total_capacity and free_space information is updated.
NetBackup uses free_space, potential_free_space, and committed_space to determine how much space is available on a disk. It uses the following formula:
available space = free_space + potential_free_space - committed_space
-listmediaid lists all disk volumes that have been given a disk media ID.
Sets the list type to dump debug data. This option dumps information without further processing. The output format and displayed fields are subject to change without notification.
Specifies the name of the disk pool to be queried. This pool is the data storage area for this storage unit.
Displays the status for only the specified disk volume. For NearStore, the input value is the volume path. For BasicDisk, the input value is the path. In all other cases, the input value is the volume name.
Sets the list type to short. This option produces parsable output with all fields on one line, no headers. The first field indicates the version of the output as an aid to the script operation. Date and time values appear in UNIX long format; status values appear in integer form.
Lists all imported disk pools in the NetBackup database. For an OpenStorage disk, -listdp lists all the disk pools that have been configured.
Lists the status for all disk volumes of imported disk pools and returns a list of all disk volumes in the NetBackup database. See Example 3.
Lists NetBackup Disk Service Manager global disk attributes. If SPR is enabled, the SCSI Persistent Reservation setting is set to one (1). If LUN masking is enabled, the output shows zero (0) rather than 1.
Lists all disk volumes that have been given the specified disk media IDs.
Lists all servers that host storage. These include appliances such as OpenStorage, SAN-attached storage such as SharedDisk (NetBackup 6.5 media servers only), BasicDisk, and Network-attached storage (NAS devices) such as NetApp.
The host name of the storage server. For NearStore, this name is the hostname of the NearStore system. For BasicDisk, the name of the media server. In all other cases, this option is the name given to the storage server when it was created.
Specifies the string that identifies the storage server type.
Lists the configuration information about the specified disk pool, storage server, or disk storage (see Example 1). Some of the items cannot be changed.
# nbdevquery -liststs -stype AdvancedDisk -U Storage Server : <machine_name> Storage Server Type : AdvancedDisk Storage Type : Formatted Disk, Direct Attached State : UP Flag : OpenStorage Flag : AdminUp Flag : InternalUp Flag : SpanImages Flag : LifeCycle Flag : CapacityMgmt Flag : FragmentImages Flag : Cpr Flag : RandomWrites Flag : FT-Transfer
List all disk pools in the system. Note that SharedDisk operates on NetBackup 6.5 media servers only.
# nbdevquery -stype SharedDisk -dp disk-pool-1 V6.5 Disk-Pool-1 0 97456 97480 10 80 90 server1,server2,server3
List all disk pool information in user format.
nbdevquery -listdv -stype AdvancedDisk -U Disk Pool Name : djs_bd Disk Type : AdvancedDisk Disk Volume Name : Internal_16 Disk Media ID : @aaaab Total Capacity (GB) : 68.21 Free Space (GB) : 55.93 Use% : 17 Status : UP Flag : OkOnRoot Flag : ReadOnWrite Flag : AdminUp Flag : InternalUp Num Read Mounts : 0 Num Write Mounts : 1 Cur Read Streams : 8 Cur Write Streams : 6
Do a disk drive dump of the disk pool sim_dp1 that SharedDiski uses. Note that SharedDisk operates on NetBackup 6.5 media servers only.
