New Revision: 386
Added:
trunk/orca/lib/SE/3.3.1/tapeinfo.se
Modified:
trunk/orca/data_gatherers/orcallator/orcallator.se
Log:
This is the first update to the disk/tape data collection. More changes are in the works, but I’d like to “version” it now, so that it is easier to track what is changed.
Naming conventions are changed from RAW_disk to KSTAT_IO
Static RAW_disk array is replaced by dynamic ORCA_io_dev_info array
Short and Long device names are now “strings”, thus dynamic
raw_disk_map and name compare functions are removed and replaced by the simple name lookup using find_inst
Removed some unused variables
Added tape “long” name mapping (stxxx is being mapped to rmt/xx) support. Requires tapeinfo.se (modified version of diskinfo.se)
