KM5 FlashMemory Summary attributes

The KM5 FlashMemory Summary table contains attributes related to an LPAR's usage of SCM (Storage Class Memory).

1 Megabyte Writes Demoted Number of 1 Megabyte Pages written to SCM that were demoted to discontiguous 4K blocks.Valid value is a 4-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Active I/O Threshold This is the count of active SCM I/O output requests at which paging to Local Paging datasets (DASD) is considered as an alternative to SCM. For example, if the count of active SCM I/O output requests is greater than this value, then DASD is added to the selection criteria when deciding where to send new SCM I/O output requests. Valid value is a 4-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Backed 64-Bit Common Pages Number of 64-Bit Common Pages backed by SCM. Valid value is an 8-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Backed 64-Bit Shared Pages Number of 64-Bit Shared Pages backed by SCM. Valid value is an 8-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Backed Shared Groups Number of Shared Page Groups backed by SCM. Valid value is an 8-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Blocks In Error Number of SCM 4K blocks that are 'in error' and cannot be used. Valid value is an 8-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Deferred Non Fault Pages/Sec Count or SCM I/O output requests representing other than page-faults that are deferred to Local Page datasets (DASD). Valid value is an 8-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Deferred Page Fault Pages/Sec Count or SCM I/O output requests representing page-faults that are deferred to Local Page datasets (DASD). Valid value is an 8-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Local Paging Service Time Lowest recent service time for Local Paging Dataset requests, in microseconds, displayed as seconds to 6 decimal places. Valid value is a 4-byte integer.

LPAR Name Name of the LPAR. Valid value is a character string with max length of 8.

Managed System Managed system name where this data is collected. Valid value is a character string with a maximum length of 32. It has the format: <plexname>:<smfid>:MVSSYS. <plexname> is the sysplex this LPAR resides in. <smfid> is the system's SMF identifier.

Measurement Interval Time in seconds to thousandth of a second over which this observation is calculated. Valid value is a 4-byte integer.

Percent Used Percentage of SCM Blocks configured to the LPAR currently in use, to hundredths of a percent. Valid value is a 4-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

SCM Service Time Lowest recent service time for SCM (Storage Class Memory) requests, in microseconds, displayed as seconds to 6 decimal places. Valid value is a 4-byte integer.

SCM+Local Paging Percent Used Combined SCM and Local Page Dataset percentage utilized, to 2 decimal places. Valid value is a 4-byte integer.

SMF ID SMF ID as defined in the IEASYM or IEASYS PARMLIB members. Valid value is a character string with max length of 4.

System Name Name of the z/OS image. Valid value is a character string with max length of 8.

Total 1M Page Ins/Sec Total number of 1 Megabyte page-ins per second. Scaled to 2 decimal places. Valid value is an 8-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Total 1M Page Outs/Sec Total number of 1 Megabyte page-outs per second. Scaled to 2 decimal places. Valid value is an 8-byte integer.

Total 1M Reqs Completed/Sec Total number of 1 Megabyte SCM requests completed per second. Scaled to 2 decimal places. Valid value is an 8-byte integer.

'Unavailable' is shown when SCM (Storage Class Memory) is not enabled.

Total 1M Writes Completed/Sec Total number of 1 Megabyte SCM writes completed per second. Scaled to 2 decimal places. Valid value is an 8-byte integer.
