You should now have the CPFORMAT EXEC on the MAINT 191 disk.

Using the CPFORMAT EXEC

To use the CPFORMAT EXEC, perform the following steps:

1. Log back into MAINT. You should now have access to the CPFORMAT EXEC. You can get

brief help for CPFORMAT by using the parameter ?:

==> cpformat ?

Synopsis:

Format one or a range of DASD as page, perm, spool or temp disk space

The label written to each DASD is U<t><xxxx> where:

<t> is type - P (page), M (perm), S (spool) or T (Temp disk)

<xxxx> is the 4 digit address

Syntax is:

.-PAGE-.

>>--CPFORMAT--.-rdev--------------.--AS---+-PERM-+---------><

| <---------------< | '-SPOL-'

'-rdev1-rdev2-------'

The following example shows how to attach three 3390-3 volumes and use CPFORMAT to

format them as paging space. Refer to the planning work sheets that you filled out in 2.7.2,

“z/VM DASD worksheet” on page 17.

2. The DASD that will be used for paging volumes in this example are at real addresses

6285,

6286, and 6287. Query the DASD devices to see their status:

==> q 6285 6286 6287

DASD 6285 UM6285 , DASD 6286 UM6286 , DASD 6287 UM6287

3. Attach the devices to MAINT (the last parameter of * means the current user ID) using the

ATTACH command:

==> att 6285-6287 *

6285-6287 ATTACHED TO MAINT

4. Use the CPFORMAT command with the AS PAGE parameter:

==> cpformat 6285-6287 as page

Format the following DASD:

TargetID Tdev OwnerID Odev Dtype Vol-ID Rdev StartLoc Size

MAINT 6285 MAINT 6285 3390 FR6285 6285 0 3339

TargetID Tdev OwnerID Odev Dtype Vol-ID Rdev StartLoc Size

MAINT 6286 MAINT 6286 3390 FR6286 6286 0 3339

TargetID Tdev OwnerID Odev Dtype Vol-ID Rdev StartLoc Size

MAINT 6287 MAINT 6287 3390 FR6287 6287 0 3339

WARNING - this will destroy data!

For 3390-9 volumes: If you are installing onto 3390-9s, only one more paging volume

may be adequate to start. This will give you two full volumes, or the equivalent of six

3390-3s.
