Hello All
I’ve made the decision to switch my storage server from FreeNAS to Solaris. I opted to use FreeNAS as it has ZFS and until BTRFS is stable, it’s the best option (IMHO) for backup and network storage.
The switch was facilitated by the USB stick that FreeNAS was on got lost during a... (1 Reply)

devctl
DEVCTL(8) BSD System Manager's Manual DEVCTL(8) NAME
devctl -- device control utility SYNOPSIS
devctl attach device devctl detach [-f] device devctl disable [-f] device devctl enable device devctl suspend device devctl resume device devctl set driver [-f] device driver DESCRIPTION
The devctl utility adjusts the state of individual devices in the kernel's internal device hierarchy. Each invocation of devctl consists of a single command followed by command-specific arguments. Each command operates on a single device specified via the device argument. The device may be specified either as the name of an existing device or as a bus-specific address. More details on supported address formats can be found in devctl(3). The following commands are supported: attach device Force the kernel to re-probe the device. If a suitable driver is found, it is attached to the device. detach [-f] device Detach the device from its current device driver. If the -f flag is specified, the device driver will be detached even if the device is busy. disable [-f] device Disable a device. If the device is currently attached to a device driver, the device driver will be detached from the device, but the device will retain its current name. If the -f flag is specified, the device driver will be detached even if the device is busy. enable device Enable a device. The device will probe and attach if a suitable device driver is found. Note that this can re-enable a device dis- abled at boot time via a loader tunable. suspend device Suspend a device. This may include placing the device in a reduced power state. resume device Resume a suspended device to a fully working state. set driver [-f] device driver Force the device to use a device driver named driver. If the device is already attached to a device driver and the -f flag is speci- fied, the device will be detached from its current device driver before it is attached to the new device driver. If the device is already attached to a device driver and the -f flag is not specified, the device will not be changed. SEE ALSO
