Creating a Nonsystem Volume Set
There are four basic steps that you need to take to create a nonsystem
volume set for your HP 3000. It involves planning, configuration, and
finally, using VOLUTIL to add the set to your system in the following
sequence:
* Plan the volume set's definition and use. Determine the disk
drives that you need (removable media, capacity), the volume
classes, and the account structure. Plan for future expansion,
and keep the volume sets small.
* Order, receive, and connect the hardware. Use SYSGEN's ADEV
command to configure the disk drives. Refer to Chapter 3 for
more information on adding devices to the system.
* Mount the volumes in the volume set and enter the command DSTAT
ALL to make sure that they have scratch or unknown status. (You
will see volume status for all mounted volumes in system and
nonsystem volume sets.)
* To define the volume set, volumes, and classes, first reboot the
system with your new configuration and then use VOLUTIL.
The remainder of this section explains the fourth step, using VOLUTIL to
add a non-system volume set. For more detailed information refer to the
Volume Management Reference Manual (32650-90045).
To access VOLUTIL
No special capability is needed to start VOLUTIL but you must have use
volumes (UV) capability to reserve or access volume sets and create
volumes (CV) capability to modify volumes. The RECOVER command requires
system manager (SM) capability. The SHOWSET command may be used by any
user to display volume set information.
To start VOLUTIL, at the MPE prompt enter:
:VOLUTIL
To use online help
You can display helpful information about any of the VOLUTIL commands on
the screen. To do so, enter the HELP command at the volutil: prompt in
one of two forms:
* To get help for a specific command, type HELP and then the command
name. For example, to display a description, the syntax, and
examples of the NEWSET command, enter:
volutil:HELP NEWSET
* To see a list of all the VOLUTIL commands with a brief description
of each one, simply enter HELP or H.
To define the volume set
You define a new volume set by initializing the master of the volume set.
Define the volume set with the NEWSET command, including the set name,
master volume name, and the LDEV.
NEWSET has the following parameters:
NEWSET {[SNAME] = sname} {[MASTER] = master} {[LDEV] = ldev}
[[PERM] = percentperm] [[TRANS] = percenttrans] [[GEN] = gen_number]
[[CLASSES] = cname[,cname][,...]]
To define the volume set PROD to be created on logical device 18 with
master volume name MASTER and with permanent disk space set to 100
percent, enter:
volutil:NEWSET SNAME=PROD MASTER=MASTER LDEV=18 PERM=100
Nonsystem volumes use only permanent space, which you should set to 100.
The system issues recovery messages each time a volume is mounted. The
following example illustrates this:

To add members to the volume set
Use the NEWVOL command to add or define a second or member volume of the
volume set and initialize it. NEWVOL has the following parameters:
NEWVOL has the following parameters:
NEWVOL {[VNAME] = sname:vname} [[LDEV] = ldev] [[PERM] = percentperm]
[[TRANS] = percenttrans] [[CLASSES] = cname[,cname][,...]]
To prevent errors, the set name and volume name are required, but you may
supply both at once in the VNAME position, separated by a colon. The
ldev parameter is optional, though if you do not enter an LDEV, you must
initialize the volume you are adding in a separate step. If you do
supply the LDEV number, the volume is defined, initialized, then
automatically recognized and mounted.
To add a member volume, do the following:
1. Start VOLUTIL by entering VOLUTIL at the MPE prompt.
2. At the volutil: prompt, enter:
volutil:NEWVOL sname:vname additional parameters
For example, to add PRODMEMBER1 to the volume set PROD as LDEV 25,
enter:
volutil:NEWVOL VNAME=PROD:PRODMEMBER1 LDEV=25
3. Enter the VSCLOSE command to post the new volume label information
to disk.
4. Enter VSOPEN to make the new volume available to users.
NOTE If you do not enter an LDEV number, the volume is added but not
initialized. To initialize the volume later, use the INITVOL
command. At the volutil: prompt, enter:
volutil:INITVOL sname:vname ldev
For example, to initialize PROD:PRODMEMBER2 specifying logical
device 25 and using positional parameters, enter:
volutil:INITVOL PROD:PRODMEMBER2 25
To create volume classes
Use the NEWCLASS command to define volume classes within a set. NEWCLASS
has the following syntax:
NEWCLASS {[CNAME] = sname:cname} [[VOLUMES] = vname[,vname][,...]]
To add a class, do the following:
1. Start VOLUTIL by entering VOLUTIL at the MPE prompt.
2. At the volutil: prompt, enter:
volutil:NEWCLASS sname:vname parameter
For example, to add the new class ORDERS to PROD and to assign the
volume PRODMASTER to ORDERS, enter:
volutil:NEWCLASS CNAME=PROD:ORDERS VOLUMES=PRODMASTER
3. Enter Y when prompted to verify the EXPANDCLASS command.
To add additional volumes to an existing volume class
Use the EXPANDCLASS command to add a volume or volumes to a class.
EXPANDCLASS has the following syntax:
EXPANDCLASS {[CNAME] = sname:cname} [[VOLUMES] = vname[,vname][,...]]
To add a volume or volumes to an existing class, do the following:
1. Start VOLUTIL by entering VOLUTIL at the MPE prompt.
2. At the volutil: prompt, enter:
volutil:EXPANDCLASS sname:vname parameter
For example, to add the volume PRODMEMBER2 to PROD:ORDERS, enter:
volutil:EXPANDCLASS CNAME=PROD:ORDERS VOLUMES=PRODMEMBER2
3. Enter Y when prompted to verify the EXPANDCLASS command.
4. Enter the VSCLOSE command to post the new volume label information
to disk.
5. Enter VSOPEN to make the new volume available to users.
To display information about volume sets
Use the SHOWSET command to display information about the volume set.
To display volume set information, at the volutil: prompt, enter:
volutil:SHOWSET sname parameters
SHOWSET has the following parameters:
[ {CLASSES}]
[ {VOLUMES}]
SHOWSET [[SNAME] = sname] [[INFO] = {SETINFO}]
[ {DSTATUS}]
[ {LABELS }]
[ {STRUCT }]
For example, to display a summary of the current structure or
class/volume hierarchy for PROD, enter:
volutil:SHOWSET SNAME=PROD INFO=STRUCT
Below is an example of the kind of information you will see. The
asterisk before PRODMEMBER2 means that the volume has been defined, but
not initialized.
