Examine the /proc/driver/z90crypt file to ensure that all options are set correctly.
When the rcz90crypt and rcpkcsslotd daemons are running, issue
this command on the SSL client and server machines to show the statistics
of the CEX2A SSL handshake acceleration. To see the contents of the /proc/driver/z90crypt file,
issue the following command:
cat /proc/driver/z90crypt The output is similar to these lines. Bold is used for emphasis
and is not part of the command output.

The
following list describes each of the significant fields of the /proc/driver/z90crypt file.
- Cryptographic domain: 8
- The processors reside in domain number 8.
- Total device count: 2 and CEX2A count: 2
- There are two cryptographic processors, and they are both configured as CEX2A (accelerator) devices.
- Online device list
- The CEX2A processors are denoted by the number 6 in this list, in positions 5 and 7. This position is the same position in their cryptographic candidate list.
- Per-device successfully completed request counts list
- The successfully completed device counts show the number (in hexadecimal)
of packet transmissions over the CEX2A adapter. They are also in positions
5 and 7, reflecting the positions assigned during cryptographic card
configuration.
The packet count shows the utilization of the processors for SSL handshakes, with eight digits for each queue.
- Waiting work element counts list
- When elements are reported here, the corresponding processor is over utilized. Each digit represents one queue.
