Viewing Histograms for Ports
• To view histogram data for ports, issue the histport command.
By default, only histogram data for data transfers are displayed. You can optionally display
histogram data for control transfers or both data and control transfers by issuing the histport
-ctl or histport -both command, respectively.
Histogram data output can be further refined to display only port data from:
◦ specific nodes.
◦ specific PCI slots.
◦ specific port slots.
◦ host-connected (target) ports.
◦ disk-connected (initiator) ports.
◦ Fibre Channel ports (for Remote Copy).
◦ Ethernet ports (for Remote Copy).
You can use additional filters to refine the histogram data output and specify how that data
is displayed. Refer to the InForm OS Command Line Reference for complete details about
histport command options and for sample command data output.
Viewing Histograms for VLUNs
• To view histogram data for VLUNs, issue the histvlun command.
Histogram data output can be further refined to display only VLUN data from:
◦ specific domains.
◦ specific hosts.
◦ specific virtual volumes.
◦ specific LUNs.
◦ ports from specific nodes, slots, or ports.
You can use additional filters to refine the histogram data output and specify how that data
is displayed. Refer to the InForm OS Command Line Reference for complete details about
histvlun command options and for sample command data output.
Viewing Histograms for Virtual Volumes
• To view histogram data for virtual volumes, issue the histvv command.
• To view histogram data for remote copy virtual volumes, issue the histrcvv command.
You can use additional filters to refine the histogram data output and specify how that data
