Use the DISPLAY ASM command to identify the page data sets and storage-class memory (SCM) blocks that the system
is currently using. You can request this information for each data
set of a given type, or for a specific data set.
If you request information by data set type, the following information
is displayed in message IEE200I for each data set of the specified
type that the system is currently using:
- Type of data set
- Percent full
- Status
- Device number
- Data set name
If you request information about the
PLPA or
common data set, or about a specific
page data
set, you receive all the preceding information, plus:
- Volume serial number
- Device type
- Data set size (in slots)
- Number of slots that are currently in use
- Number of slots that are currently available
- Number of permanent I/O errors that have occurred on the specified
data set

- ASM
- The system is to display information about the
page data sets and storage-class memory (SCM) the
system is currently using. If you specify DISPLAY ASM with no operands,
the system displays information about all page data sets and SCM that it is currently
using and the status of the PAGEDEL command.
- PLPA
- Requests information about the PLPA page data set.
- COMMON
- Requests information about the common page data set.
- LOCAL
- Requests information about all local page data sets.
- SCM
- Requests information about storage-class memory (SCM) that is used for paging.
- ALL
- Requests information about all page data sets, storage-class memory (SCM) and the status of the PAGEDEL command.
- PAGE
- Requests information about page data sets.
- ALL
- Requests information about all page data sets.
- dsname
- Requests information about the page data set named dsname.
- PAGEDEL
- Requests information about the PAGEDEL command, active or inactive.
- L=a, name, or name-a
- Specifies the display area (a), console name (name),
or both (name-a) where the display is to appear.
If you omit this operand, the display is presented in the first available
display area or the message area of the console through which you
enter the command.
Example 1:
To display summary information about all page data
sets,
storage-class memory (SCM) and the PAGEDEL
command status, enter:
DISPLAY ASM,ALL or D ASM
Output is similar to:
TYPE FULL STAT DEV DATASET NAME
PLPA 100% FULL 02E6 SYS1.PLPA.PAGCOM
COMMON 71% OK 02E6 SYS1.COMMON.PAGCOM
LOCAL 1% OK 098E SYS1.LOCAL.PAGEP2
LOCAL 1% OK 0981 SYS1.COMMON
LOCAL 0% OK 0484 PAGE2
SCM 5% OK N/A N/A
PAGEDEL COMMAND IS NOT ACTIVE
Example 2:
To display detailed information about
storage-class memory (SCM),
enter:
D ASM,SCM
Output is similar to:
STATUS FULL SIZE USED IN-ERROR
IN-USE xxx% xx,xxx,xxx,xxx xx,xxx,xxx,xxx xx,xxx,xxx,xxx
Note: If the D ASM,SCM command is issued and storage-class memory (SCM) is not
being used for paging, message IEE207I is issued with a status value
of NOT-USED, even if SCM is defined to the partition.
To display detailed information about the PLPA data set, enter:
D ASM,PLPA
Example 3:
To display only paging data set information,
enter:
D ASM,PAGE or D ASM,PAGE=ALL
D
ASM,PAGE output is similar to:
TYPE FULL STAT DEV DATASET NAME
PLPA 100% FULL 02E6 SYS1.PLPA.PAGCOM
COMMON 69% OK 02E6 SYS1.COMMON.PAGCOM
LOCAL 0% OK 098E SYS1.LOCAL.PAGEP2
LOCAL 0% OK 0981 SYS1.COMMON
LOCAL 0% OK 0484 PAGE2
D ASM,PAGE=ALL output is similar
to:
TYPE FULL STAT DEV DATASET NAME
PLPA 100% FULL 02E6 SYS1.PLPA.PAGCOM
COMMON 69% OK 02E6 SYS1.COMMON.PAGCOM
LOCAL 0% OK 098E SYS1.LOCAL.PAGEP2
LOCAL 0% OK 0981 SYS1.COMMON
LOCAL 0% OK 0484 PAGE2
