Continued Metric Write Cache Hits Categories ARRAY LUN Description Usage The number of cache page accesses that were satisfied immediately from data that was stored in the write cache when processing host write commands A host write command that spans multiple write cache pages will count a write cache hit for each write cache page that was immediately available in the write cache when the write command was processed Any delays in accessing cache pages due to write cache posts or due to address conflicts with data in the cache being read or written to disk will not be counted as a write cache hit A cache page access that causes the allocation of a new write cache page from the pool of free write cache pages without waiting for a write cache post to complete is counted as a write cache hit Usage The ratio of Write Cache Hits to Cache Pages Written gives a general indication of the effectiveness of the write cache in servicing the host write workload The write cache serves primarily as a buffer to absorb bursts of high write activity in the host workload and provide a low latency response then write the data to disk during a time of lower activity All data that comes into the write cache will eventually be written to disk If this ratio is near one that is an indication that there is an approximate one to one correspondence between incoming and outgoing writes In that case a high percentage of the incoming writes will ha
15. If the changes to the firmware do not impact the mapping of controller memory the on line procedure can be used This procedure is faster than the off line download because it only involves a reset to the array If the changes to the firmware alter the controller memory mapping the on line procedure cannot be used The off line procedure must be used in this situation A change to the memory mapping requires that the array perform a shutdown and restart which is performed as part of the off line procedure Note When downloading controller firmware always check the README file included with the firmware If you have access you can also read the HP Service Note associated with the firmware download This information will identify whether you can perform the firmware download offline or online When downloading firmware off line using the CLUI the Command View SDM GUI should not be running in the background There is a possibility that the GUI will not adapt to new array automatically The GUI will have to be closed and restarted following the firmware download Examples Disk Module Download This example illustrates one method for downloading new firmware to the disk modules Firmware is downloaded to all disks The firmware file is located in the default firmware directory 1 Identify the current product numbers and firmware versions of the disk modules on the array with alias MyArray armdownload I D MyArray 128 Command Line

Line User Interface Table 10 Performance Metrics Continued Metric Categories Description Usage Number of Forced Unit Access ARRAY The number of host read and write commands processed Commands LUN while the Forced Unit Access condition was in effect When the Forced Unit Access condition is in effect for a read command any data in the read cache addressed by the read command is discarded and fetched from disk again When the Forced Unit Access condition is in effect for a write command any data in the write cache for the LUN addressed by the write command is posted to disk before the write command is processed When the write command is processed it is posted to disk before completion status is reported to the host The table below indicates when the Forced Unit Access condition is in effect Usage Normally read commands that address data completely contained in the read cache will be satisfied by reading the data from the read cache rather than from disk Normally write commands will report completion after the write data has been placed into the write cache and before it is written to disk The Forced Unit Access condition causes host reads to be satisfied from disk and host writes to be written to disk before completion is reported to the host Operating in Forced Unit Access mode can significantly reduce performance especially for writes Firmware releases HP13 and prior Firmware releases after HP13 Array mode FUA requeste
