To explicitly enable multipathing on this HBA port, but disable on the rest of the HBA ports, add the following: MODIFICAR /kernel/drv/scsi_vhci.conf # For enabling MPxIO support for 3rd party symmetric device need an # entry similar to following in this file. Just replace the "SUN SENA" # part with the Vendor ID/Product ID for the device, exactly as reported by # Inquiry cmd. # # device-type-scsi-options-list = # "SUN SENA", "symmetric-option"; # # symmetric-option = 0x1000000; device-type-scsi-options-list = "HP OPEN-V*4", "symmetric-option"; <== iostat -En Add the vendor ID and product ID entries. symmetric-option = 0x1000000; MODIFICAR /kernel/drv/fp.conf # You can also enable or disable MPxIO on a per port basis. # Per port settings override the global setting for the specified ports. # To disable MPxIO on port 0 whose parent is /pci@8,600000/SUNW,qlc@4 set: # name="fp" parent="/pci@8,600000/SUNW,qlc@4" port=0 mpxio-disable="yes"; # name="fp" parent="/pci@300/pci@1/pci@0/pci@4/SUNW,emlxs@0" port=0 mpxio-disable="no"; <== luxadm -e port To enable multipathing on a HBA port, add name="fp" parent="/pci@300/pci@1/pci@0/pci@5/SUNW,emlxs@0" port=0 mpxio-disable="no"; <== luxadm -e port To enable multipathing on a HBA port, add # NOTE: If you just want to enable or disable MPxIO on all fp ports, it is # better to use stmsboot(1M) as it also updates /etc/vfstab. # mpxio-disable="yes"; <== set yes To disable multipathing globally, change to: # reboot -- -r The vendor ID and product ID are the vendor and product indentification strings that the device returns in SCSI INQUIRY data. The vendor ID must be eight characters long. You must specify all eight characters (even if the trailing characters are spaces). The product ID can be up to 16 characters long. |
BASH HOTKEYS
Bash provides many hot keys to ease use. Like
ctrl-l -- clear screen
ctrl-r -- does a search in the previously given commands so that you don't
have to repeat long command.
ctrl-u -- clears the typing before the hotkey.
ctrl-a -- takes you to the begining of the command you are currently typing.
ctrl-e -- takes you to the end of the command you are currently typing in.
esc-b -- takes you back by one word while typing a command.
ctrl-c -- kills the current command or process.
ctrl-d -- kills the shell.
ctrl-h -- deletes one letter at a time from the command you are typing in.
ctrl-z -- puts the currently running process in background, the process
can be brought back to run state by using fg command.
esc-p -- like ctrl-r lets you search through the previously given commands.
esc-. -- gives the last command you typed.
