• HP StorageWorks 8/40 SAN Switch • HP StorageWorks 400 Multi-Protocol Router • HP StorageWorks DC SAN Backbone Director • HP StorageWorks DC04 SAN Director Switch For the HP StorageWorks 4/256 SAN Directors, the maximum number of filters is 12 per port in any combination of standard filters and user-defined filters, except for the HP StorageWorks SAN Director 48 Port 4Gb FC blade. For the HP StorageWorks SAN Director 48 Port 4Gb FC blade: • The lower 16 ports (ports 0 through 15) have a maximum of 12 filter monitors per port and 15 offsets per port for user-defined monitors. • The middle 16 ports (ports 16 through 31) have a maximum of 6 filter monitors per port and 11 offsets per port for user-defined monitors. • The upper 16 ports (ports 32 through 47) do not support filter monitors. The actual number of filters that can be configured on a port depends on the complexity of the filters. For trunked ports, the filter is configured on the trunk master. Virtual Fabrics considerations: Filter-based monitors are not supported on logical ISLs (LISLs), but are supported on ISLs and extended ISLs (XISLs). You can monitor filter-based performance using the perfMonitorShow command, as described in "Displaying monitor counters" on page 418. You can clear filter-based counters using the perfMonitorClear command, as described in "Clearing monitor counters" on page 420. Adding standard filter-based monitors You cannot add identical filter monitors to the same port. Two filter monitors are considered to be identical when they have the same values for the following items: • Filter monitor type • Owner (Telnet, Web Tools, etc.) • Alias 1. Connect to the switch and log in as admin. 2. Enter one of the following commands, depending on the type of monitor you want to add: • perfAddReadMonitor to count the number of SCSI Read commands • perfAddWriteMonitor to count the number of SCSI Write commands • perfAddRwMonitor to count the number of SCSI Read and Write commands • perfAddScsiMonitor to count the number of SCSI traffic frames • perfAddIpMonitor to count the number of IP traffic frames See the Fabric OS Command Reference for complete descriptions of these commands.
