NAME¶
lszcrypt - display zcrypt device and configuration information
SYNOPSIS¶
- lszcrypt
- [ -V | -VV ] [ <device id>
[...]]
- lszcrypt -b
- lszcrypt -h
- lszcrypt -v
DESCRIPTION¶
The
lszcrypt command is used to display information about cryptographic
adapters managed by zcrypt and zcrypt's AP bus attributes. Displayed
information depends on the kernel version.
lszcrypt requires that the
sysfs filesystem is mounted.
The following information can be displayed for each cryptographic adapter: card
type, online status, hardware card type, hardware queue depth, and request
count. The following AP bus attributes can be displayed: AP domain,
configuration timer, poll thread status, poll timeout, and AP interrupt
status.
OPTIONS¶
- -V, --verbose
- Increase verbose level for cryptographic adapter
information. Maximum verbose level is two. At verbose level one card type
and online status are displayed. At verbose level two card type, online
status, hardware card type, hardware queue depth, and request count are
displayed.
- <device id>
- Specifies a cryptographic adapter which will be displayed.
A cryptographic adapter can be specified either in decimal or hexadecimal
notation using a '0x' prefix. If no adapters are specified information
about all available adapters will be displayed.
- -b, --bus
- Show AP bus attributes and exit.
- -h, --help
- Print help text and exit.
- -v, --version
- Print version information and exit.
EXAMPLES¶
- lszcrypt -V
- Will display card type and online status of all available
cryptographic adapters.
- lszcrypt -VV 0 1 10 12
- Will display card type, online status, hardware card type,
hardware queue depth, and request count for cryptographic adapters in
decimal notation 0, 1, 10, and 12.
- lszcrypt -b
- Will display AP bus information.
