Table 63. Statistic collection for volume cache per individual nodes (continued). This table
describes the volume cache information that is reported for individual nodes.
ctrhs Indicates the total number of sectors that are read for reads received from
other components that obtained total cache hits on prestage or non-prestage
data.
ctr Indicates the total number of track reads received. For example, if a single
read spans two tracks, it is counted as two total track reads.
ctrs Indicates the total number of sectors that are read for reads received.
ctwft Indicates the number of track writes received from other components and
processed in flush through write mode.
ctwfts Indicates the total number of sectors that are written for writes that are
received from other components and processed in flush through write mode.
ctwfw Indicates the number of track writes received from other components and
processed in fast-write mode.
ctwfwsh Indicates the track writes in fast-write mode that were written in
write-through mode because of the lack of memory.
ctwfwshs Indicates the track writes in fast-write mode that were written in write
through due to the lack of memory.
ctwfws Indicates the total number of sectors that are written for writes that are
received from other components and processed in fast-write mode.
ctwh Indicates the number of track writes received from other components where
every sector in the track obtained a write hit on already dirty data in the
cache. For a write to count as a total cache hit, the entire track write data
must already be marked in the write cache as dirty.
ctwhs Indicates the total number of sectors that are received from other components
where every sector in the track obtained a write hit on already dirty data in
the cache.
ctw Indicates the total number of track writes received. For example, if a single
write spans two tracks, it is counted as two total track writes.
ctws Indicates the total number of sectors that are written for writes that are
received from components.
ctwwt Indicates the number of track writes received from other components and
processed in write through write mode.
ctwwts Indicates the total number of sectors that are written for writes that are
received from other components and processed in write through write mode.
cv Indicates the number of sectors of read and write cache data that is held in
the cache.
Table 64 describes the XML statistics specific to an IP Partnership port.
Table 64. XML statistics for an IP Partnership port
Statistic
name Description
ipbz Indicates the average size (in bytes) of data that are being submitted to the IP
partnership driver since the last statistics collection period.
ipre Indicates the bytes retransmitted to other nodes in other clusters by the IP
partnership driver.
iprt Indicates the average round-trip time in microseconds for the IP partnership
link since the last statistics collection period.
