chzcrypt - Modify the cryptographic configuration

Use the chzcrypt command to configure cryptographic adapters that are managed by the cryptographic device driver and modify the AP bus attributes.

To display the attributes, use the lszcrypt command.

Where:
-e or --enable
sets the given cryptographic adapters online.
-d or --disable
sets the given cryptographic adapters offline.
-a or --all
sets all available cryptographic adapters online or offline.
<device ID>
specifies a cryptographic adapter that is to be set online or offline. A cryptographic adapter can be specified either in decimal notation or hexadecimal notation with a '0x' prefix.
-p or --poll-thread-enable
enables the poll thread of the cryptographic device driver.
-n or --poll-thread-disable
disables the poll thread of the cryptographic device driver.
-c <timeout> or --config-time <timeout>
sets configuration timer for rescanning the AP bus to <timeout> seconds.
-t <time>or --poll-timeout=<time>
sets the high-resolution polling timer to <time> nanoseconds. To display the value, use lszcrypt -b.
-V or --verbose
displays verbose messages.
-v or --version
displays version information.
-h or --help
displays help information for the command. To view the man page, enter man chzcrypt.

Examples

These examples illustrate common uses for chzcrypt.

  • To set the cryptographic adapters 0, 1, 4, 5, and 12 online (in decimal notation):
    chzcrypt -e 0 1 4 5 12
  • To set all available cryptographic adapters offline:
    chzcrypt -d -a
  • To set the configuration timer for rescanning the AP bus to 60 seconds and disable the poll thread of the cryptographic device driver:
    chzcrypt -c 60 -n
