Using the CPFORMAT EXEC

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

help on CPFORMAT by using a parameter of ?:

==> cpformat ?

Synopsis:

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

The label written to each DASD is M<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 illustrates how to attach five 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.

Rather than using five consecutive DASD addresses, you may consider using DASD from

different address ranges in an attempt to locate the paging volumes on different

ranks in your

disk array. This should enable z/VM to page more efficiently.

1. The DASD that will be used for paging volumes are at real addresses

D855, D950, D951,

DA50

and DB50. First query the DASD devices to see their status:

==> q <d855 d950 d951 da50 db50>

DASD D855 NWD855 , DASD D950 NWD950 , DASD D951 NWD951 , DASD DA50 NWDA50

DASD DB50 NWDB50

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

ATTACH command:

==> att <d855 d950 d951 da50 db50> *

D855 D950 D951 DA50 DB50 ATTACHED TO MAINT

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

==> cpformat d855 d950 d951 da50 db50 as page

Format the following DASD:

TargetID Tdev OwnerID Odev Dtype Vol-ID Rdev StartLoc Size

MAINT D855 MAINT D855 3390 NWD855 D855 0 3339

TargetID Tdev OwnerID Odev Dtype Vol-ID Rdev StartLoc Size

MAINT D950 MAINT D950 3390 NWD950 D950 0 3339

TargetID Tdev OwnerID Odev Dtype Vol-ID Rdev StartLoc Size

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 same equivalent of six

3390-3s.

For example, if your z/VM system installed onto DASD at D850-D852 and you plan to put the

second paging volume on D853, then only that volume needs to be added.
