Diagnostics 3 Memory test Use the BCU or the HCM to perform a memory test for the adapter. NOTE Performing the memory test disables the adapter. Performing a memory test through BCU Use the diag --memtest command to test the adapter's memory blocks. diag --memtest where: ad_id ID of the adapter. Performing a memory test through HCM Use the Hardware Tests tab on the Diagnostics dialog box as follows to perform a memory test. 1. Launch the HCM. 2. Select Configure > Diagnostics. 3. Click the Hardware Tests tab. 4. Select Memory Test. 5. Specify the test cycle using a positive number. 6. Click Start. Pinging Fibre Channel end points Use the BCU and HCM to ping a Fibre Channel end point from an adapter port to determine the basic connectivity to the remote port and monitor network latency. NOTE Ping testing is not supported on Solaris systems. Issuing a ping command to end points through BCU Use the fcdiag --fcping BCU command to test the connection to a Fibre Channel end point. fcdiag --fcping [-l ] where: port_id rpwwn lpwwn ID of the adapter port from which you want to ping the remote port. This could be the PWWN, port hardware path, or user-specified port name. This could also be the adapter-index/port-index. For example, to specify adapter 1, port 1, you would use 1/1 as the port identification. Remote PWWN that you want to ping. Logical PWWN. 0 indicates the base port.

Diagnostics
3
Memory test
Use the BCU or the HCM to perform a memory test for the adapter.
NOTE
Performing the memory test disables the adapter.
Performing a memory test through BCU
Use the
diag --memtest
command to test the adapter’s memory blocks.
diag --memtest <ad_id>
where:
ad_id
ID of the adapter.
Performing a memory test through HCM
Use the
Hardware Tests
tab on the
Diagnostics
dialog box as follows to perform a memory test.
1.
Launch the HCM.
2.
Select
Configure > Diagnostics
.
3.
Click the
Hardware Tests
tab.
4.
Select
Memory Test
.
5.
Specify the test cycle using a positive number.
6.
Click
Start
.
Pinging Fibre Channel end points
Use the BCU and HCM to ping a Fibre Channel end point from an adapter port to determine the
basic connectivity to the remote port and monitor network latency.
NOTE
Ping testing is not supported on Solaris systems.
Issuing a ping command to end points through BCU
Use the
fcdiag --fcping
BCU command to test the connection to a Fibre Channel end point.
fcdiag -–fcping <port_id> <rpwwn> [-l <lpwwn>]
where:
port_id
ID of the adapter port from which you want to ping the remote port. This could
be the PWWN, port hardware path, or user-specified port name. This could
also be the adapter-index/port-index. For example, to specify adapter 1, port
1, you would use 1/1 as the port identification.
rpwwn
Remote PWWN that you want to ping.
lpwwn
Logical PWWN. 0 indicates the base port.
