• -images are discovered Images (FCUB).
• -emul represents emulated FDCBs.
• -active represents active FDCBs.
• -epcb is the emulation Control Block (port specific).
• -fhpb is the FICON Host Path Block.
• -fdpb adrs is the FICON Device Path Block.
• -fchb is the FICON Channel Control Block.
• -fcub is the FICON Control Unit Control Block.
• -fdcb adrs is the FICON Device Control Block.
• -mem adrs displays 1250 memory in 256 byte increments.
• -pools displays current data buffer pool counts.
• -pmmr displays PMMR pointers.
• -clear clears statistics.
The -emul argument can be used to Monitor FICON emulation activities (see ”FICON emulation
monitoring” on page 447). The other arguments are primarily for support personnel.
FICON emulation monitoring
The -emul argument can be used to monitor FICON emulation. The following is an example:
switch:admin> portshow ficon ge1 0 -emul
XRC and Tape statistics are presented in different output formats.The following elements are common to
both tape emulation and XRC emulation outputs:
• FDCB ptr is a pointer to the FICON Device Control Block. Support personnel may use this pointer.
• Path is the device path, in the format VE-HD-HP-DD-DP-LP-CU-DV. where:
• VE is the internal VE_Port number.
• HD is the hex value for the Host Domain (the entry domain for this host port into the fabric).
• HP is the hex value for the Host Port (the entry port of this host connection into the fabric).
• DD is the hex value for the Device Domain (the entry domain for this device into the fabric).
• DP is the hex value for the Device Port (the entry port for this device connection into the fabric).
• LP is the Logical Partition (LPAR) value for the host accessing the specific device.
• CU is the Control Unit number (CUADDR) for the specific FICON connection.
• DV is the Device Number of this FICON connected device.
For example, the value 2463016406050001 breaks down as follows:
• State is displayed as a value of zero indicates emulation is idle. Any non-zero value indicates emulation
is active.
