# sanlk-reset(8)

host reset program

## NAME

sanlk-reset - host reset program

## SYNOPSIS

**sanlk-reset** \[OPTIONS\] *action* *lockspace\_name* ...

## DESCRIPTION

The sanlk-reset program sets events in specified sanlock lockspaces. Events are defined to cause sanlk-resetd on another host to:\
 \- use wdmd/watchdog to reset the host\
 \- use /proc/sysrq-trigger to reboot the host

Both hosts must be operational and have continued access to a common lockspace for the reset request to succeed.  After setting the event, the sanlk-reset program monitors the host status in the sanlock lockspace until the target host is dead.

The sanlk-reset program can also be run on the same host as sanlk-resetd to update which lockspaces the local sanlk-resetd is watching for events.

## OPTIONS

- **--version, -V**

  Print version.

- **--help, -h**

  Print usage.

### Reset another host

The event is set in each lockspace specified.  The target host may have a different host id in each lockspace.

**sanlk-reset reset** *lockspace\_name:host\_id* ...

- **--host-id, -i** *num*

  Host id to reset. (Use only with single lockspace name.)

- **--generation, -g** *num*

  Generation of host. (Use only with single lockspace name.)

- **--sysrq-reboot, -b 0\|1**

  Enable/Disable (1/0) use of /proc/sysrq-trigger to reboot.

- **--resource-mode, -R 0\|1**

  Resource leases are used (1) or not used (0) to protect storage.

- **--native-timeout, -t num**

  Disable native timeout by setting to 0.

### Update the local sanlk-resetd

to watch new lockspaces for reset events:

**sanlk-reset reg** *lockspace\_name* ...

to not watch lockspaces for reset events:

**sanlk-reset end** *lockspace\_name* ...

to clear all lockspaces being watched:

**sanlk-reset clear all**
