To rebuild a volume, either:
You cannot use the /REBUILD_STATUS qualifier with any other SHOW DEVICES qualifiers, except /OUTPUT.
You can also dynamically change the search string by pressing the Find key (E1) while the information is being displayed. Quotation marks are not required for a dynamic search.
If you specify the /NOSYSTEM qualifier with the /FILES qualifier, only files opened by processes are displayed. If you omit both the /SYSTEM and /NOSYSTEM qualifiers and specify the /FILES qualifier, the names of all files currently open on the system are displayed.
You can use this qualifier only with the /FILES qualifier. See the description of the /FILES qualifier for more details.
The /NOWRAP qualifier extends lines beyond the width of the screen and can be seen when you use the scrolling (left and right) features provided by the /PAGE=SAVE qualifier.

Displays information on devices served by the mass storage control protocol (MSCP) server on this node. The /SERVED qualifier is required.
SHOW DEVICES/SERVED
The SHOW DEVICES/SERVED command displays information about the MSCP server and the devices it serves. This information is used mostly by system managers. The following message displays when the user issues a SHOW DEVICE/SERVED command when the tape server is not loaded:%SHOW-E-TMSCPNOTLD, TMSCP-Server code not loaded
/ALL
This qualifier displays the information displayed by all of the qualifiers listed below except the /OUTPUT qualifier./COUNT
Displays the number of transfer operations completed, sorted by the size of the transfers, and the number of MSCP operations that have taken place since the MSCP server was started./EXACT
Use with the /PAGE=SAVE and /SEARCH qualifiers to specify a search string that must match the search string exactly and must be enclosed with quotation marks (" ").If you specify the /EXACT qualifier without the /SEARCH qualifier, exact search mode is enabled when you set the search string with the Find (E1) key.
/HIGHLIGHT[=keyword]
/NOHIGHLIGHT (default)
Use with the /PAGE=SAVE and /SEARCH qualifiers to specify the type of highlighting you want when a search string is found. When a string is found, the entire line is highlighted. You can use the following keywords: BOLD, BLINK, REVERSE, and UNDERLINE. BOLD is the default highlighting./HOST
Displays the names of the processors that have MSCP served devices on line. The System Generation utility (SYSGEN) command MSCP/HOST determines how many hosts in the OpenVMS Cluster can connect to the MSCP server at one time./OUTPUT=[filespec]
Redirects output from your terminal to the specified file. If you do not specify a file, or if you do not use this qualifier, output is sent to SYS$OUTPUT./PAGE[=keyword]
/NOPAGE (default)
Controls the display of device information on the screen.You can use the following keywords with the /PAGE qualifier:
CLEAR_SCREEN Clears the screen before each page is displayed. SCROLL Displays information one line at a time. SAVE[= n] Enables screen navigation of information, where n is the number of pages to store. The /PAGE=SAVE qualifier allows you to navigate through screens of information. The /PAGE=SAVE qualifier stores up to 5 screens of up to 255 columns of information. When you use the /PAGE=SAVE qualifier, you can use the following keys to navigate through the information:
Key Sequence Description Up arrow (<uparrow symbol>), Ctrl/B Scroll up one line. Down arrow (<downarrow symbol>) Scroll down one line. Left arrow ( <-) Scroll left one column. Right arrow (->) Scroll right one column. Find (E1) Specify a string to find when the information is displayed. Insert Here (E2) Scroll right one half screen. Remove (E3) Scroll left one half screen. Select (E4) Toggle 80/132 column mode. Prev Screen (E5) Get the previous page of information. Next Screen (E6), Return, Enter, Space Get the next page of information. F10, Ctrl/Z Exit. (Some utilities define these differently.) Help (F15) Display utility help text. Do (F16) Toggle the display to oldest/newest page. Ctrl/W Refresh the display. The /PAGE qualifier is not compatible with the /OUTPUT qualifier.
/RESOURCE
Displays information on the resources available to the MSCP server for use in processing I/O requests for the devices it serves. You make these resources available to the MSCP server when you use SYSGEN's MSCP command to start the MSCP server and use the qualifiers listed in the following table:
Qualifier Item Specified /BUFFER The amount of buffer space available to the MSCP server. /FRACTION The maximum size, in pages, of the buffer granted to an I/O request; for transfers of more data than will fit a buffer of the size specified by this qualifier, several computer interconnect (CI) transfers are needed. /SMALL The minimum size, in pages, of the buffer that the MSCP server can grant to an I/O request; if less than this amount of buffer space is available, the I/O request must wait until at least this much buffer space becomes available; when this much space becomes available, the MSCP server grants the request a buffer. /PACKETS The number of I/O-request packets (class driver request packets [CDRPs]) available to the MSCP server for processing I/O requests. /SEARCH="string"
Use with the /PAGE=SAVE qualifier to specify a string that you want to find in the information being displayed. Quotation marks are required for the /SEARCH qualifier, if you include spaces in the text string.You can also dynamically change the search string by pressing the Find key (E1) while the information is being displayed. Quotation marks are not required for a dynamic search.

This example displays the output of the SHOW DEVICES/SERVED command from a node that has both MSCP server and TMSCP server devices. In the display, the third column for MSCP server disk devices shows the size of the disk device. The same column for TMSCP server device shows the location where each tape is currently positioned.
Indicates the node where output from a DECwindows application will be displayed.
SHOW DISPLAY [display-device]
display-device
Refers to the display-device parameter specified with the SET DISPLAY command. If you are directing application output to multiple workstations in the same session, you can use logical names to point to each workstation. Using the SHOW DISPLAY command, you can specify this logical name as the display-device parameter to see where application output will be displayed.If you do not specify a display-device string, the logical name DECW$DISPLAY is used.
DECwindows gives you the ability to run applications across a network by allowing you to perform the following tasks:
- Direct the output from applications running on your workstation to another workstation.
- Direct the output from applications running on remote processors to your workstation. Although the application runs on another processor, it looks the same as any other application running locally on your workstation.
By running applications on a remote processor for local display on your workstation, you can take advantage of larger computers that might be better suited to a specific computing task. By default, applications running on your workstation are displayed on your workstation.
You use the SET DISPLAY command to direct the output from applications to other workstations. The SHOW DISPLAY command lets you see where the output from these applications will be displayed.
Sample output from the SHOW DISPLAY command looks like the following:
Device: WSA2: Node: 0 Transport: LOCAL Server: 0 Screen: 0Device is your workstation device. A new WSAn device is created each time you use the SET DISPLAY/CREATE command. Node is the network system on which the output from applications is displayed. When you are running and displaying applications on your node, Node is 0, which is the standard shorthand notation for representing your node. Transport refers to the mechanism, for example, DECNET or LOCAL, that passes information between the application---the client---and the server. The server sends input from the user to the application and output from the application to the display. Server and Screen are 0.
On DECwindows workstations, the Session Manager creates a default workstation device for use by DECwindows processes (like DECterm). When you use the SET HOST command to connect to a remote node, no workstation device is created for that process and DECW$DISPLAY is not defined. You must specifically create new display devices with the SET DISPLAY/CREATE command.
If no definition for DECW$DISPLAY exists, entering the SHOW DISPLAY command returns an error.
See the description of the SET DISPLAY command for more information.
$ SHOW DISPLAY Device: WSA1: Node: 0 Transport: LOCAL Server: 0 Screen: 0 $ SET DISPLAY/CREATE/NODE=ZEPHYR $ SHOW DISPLAY Device: WSA2: Node: ZEPHYR Transport: DECNET Server: 0 Screen: 0 $ SPAWN/NOWAIT/INPUT=NL: RUN SYS$SYSTEM:DECW$CLOCK
In this example, you are logged in to your workstation, here referred to as node 0. (0 is the standard shorthand notation for representing your node.) You want to run the DECwindows Clock on your workstation and display it on another node, ZEPHYR.
Assuming you are authorized to display applications on ZEPHYR, you redirect the application's output to ZEPHYR with the SET DISPLAY command and enter the SHOW DISPLAY command to verify the location of the redirected display. You then run Clock. Note that a new workstation display device, WSA2, is created when you enter the SET DISPLAY/CREATE command.
Displays information about a user's batch and print jobs or about specific job entries.Requires read (R) access to the queue.
SHOW ENTRY [entry-number[,...]],[job-name[,...]]
entry-number[,...]
Specifies the entry number of the job you want displayed. If no entry number or job name is specified, all your own jobs (or those owned by the user specified with the /USER_NAME qualifier) are displayed.job-name[,...]
Specifies the name of the jobs you want displayed. The asterisk (*) and the percent sign (%) wildcard characters are allowed. If no job name or entry number is specified, all your own jobs (or those owned by the user specified with the /USER_NAME qualifier) are displayed.
The SHOW ENTRY command displays information about a user's batch and print jobs or about specific job entries.The information displayed includes the entry number, the job name, the owner, job size in blocks (for print jobs), and the job status. The name, status, and queue type of the queue in which the job is located are also displayed.
If you are only interested in information about your own batch and print jobs, the SHOW ENTRY command produces a better display than the SHOW QUEUE command. Because the SHOW QUEUE command displays queue information regardless of whether your jobs are in these queues, you must scan the display to locate your jobs. By contrast, the SHOW ENTRY command displays only information relevant to your jobs (or those owned by the user you specify with the /USER_NAME qualifier). If the /USER_NAME qualifier is not specified, information about your own jobs is displayed.
/BATCH
Selects batch jobs for display./BRIEF (default)
Displays the following information for each job: entry number, job name, user name, job size in blocks (for print jobs), job status, queue name, queue status, and queue type. The /FULL and /FILES qualifiers override the /BRIEF qualifier.Specify the /FULL qualifier to obtain more job information.
/BY_JOB_STATUS[=(keyword,...)]
Selects for display only those jobs with the specified status. Specify the status with one or more of the following keywords:
EXECUTING Requests the display of jobs in any of the following states: ABORTING means that the job is halting prior to normal completion and will not continue processing. A SUSPENDED state means that the job stopped during processing, but should continue when the cause of the SUSPENDED state is resolved. A STALLED or SUSPENDED state means that the job stopped during processing, but should continue when the cause of the STALLED or SUSPENDED state is resolved. PROCESSING is the executing state for server queues. PRINTING is the executing state for printer and terminal queues. STARTING means the job is beginning to be processed.
- ABORTING
- EXECUTING
- PRINTING
- PROCESSING
- STALLED
- STARTING
- SUSPENDED
HOLDING Requests the display of jobs on hold. Holding status indicates that the job is being held in the queue indefinitely. PENDING Requests the display of jobs with pending status. Pending status indicates that the job is waiting its turn to execute. RETAINED Requests the display of jobs retained in the queue after execution. Retained status indicates that the job has completed but remains in the queue. TIMED_RELEASE Requests the display of jobs on hold until a specified time. Timed-release status indicates that the job is being held in the queue for execution at a specified time.
