Introduction

HP/HPE technical trivia

Regarding the DL380 and DL385

CPU technology: 380 = Intel; 385 = AMD
HP split into two separate companies in 2014-2015

HP will concentrate on consumer computers and printers
HPE (HP Enterprise) will concentrate on the commercial market

the HP DL380p_gen8 was the last x86-64 machine manufactured by HP
- 380p means performance; 380e mean entry level
- the gen8 is a BIOS-only machine
the HPE DL380_gen9 was the first x86-64 machine manufactured by HPE
- the gen9 is a UEFI machine

iLO (integrated Lights Out)

all modern servers built for "data center use" provide a port for remote maintenance
on HP/HPE systems this port will be labeled iLO (integrated Lights Out)
- the iLO subsystem and associated management processor will be powered up whenever at least one power supply is connected. Therefore, it is possible to power-up (and power-down) a chassis over the iLO port.
- x86 machines manufactured before 2012 usually:
  - allow iLO access via a DB-9 serial port (so you will need a data center survival kit)
  - allow ssh access via a password protected network interface (10-base-T or 100-base-T) called an iLO
- x86 machines manufactured after 2012 usually:
  - will not have a DB-9 serial port (or if they do, are totally isolated from the iLO)
  - allow ssh access via a password protected network interface which can now handle any speed up to 1-Gb/s
    - the iLO port on these machines can only be programmed from firmware (BIOS or EFI/UTEF) during boot
      -or-
    - from the HP/HPE provided maintenance program, named hponcfg, which is only available on Windows or Linux
- Itanium2 machines employ both a DB-9 serial port as well as an network interface
  (this was still true with a new rx2800-i2 I worked on which was manufactured in 2015 so you will need a data center survival kit for DB-9 access)
network access
- all modern 86x systems only support ssh connections to the iLO
- all Itanium2 systems support both telnet and ssh connections to the iLO. Telnet remains because ssh access requires that the connecting ssh client implement a handshake patch which no longer exists in Linux + Windows but is still present in all OpenVMS stacks

DMTF SMASH CLP Commands:

help    : Used to get context sensitive help.
show    : Used to display values of a property or contents of a collection target.
show  -a  : Recursively show all targets within the current target.
show  -l <level>  : Recursively show targets within the current target based on 'level' specified.
         Valid values for 'level' is from 1 to 9.
create  : Used to create new instances in the name space of the MAP.
Example: create /map1/accounts1 username=<lname1> password=<pwd12345> name= 
 <dname1> group=<admin,config,oemhp_vm,oemhp_rc,oemhp_power>

delete  : Used to destroy instances in the name space of the MAP.
Example: delete /map1/accounts1/<lname1> 

load    : Used to move a binary image from an URL to the MAP.
Example: load /map1/firmware1 -source http://192.168.1.1/images/fw/iLO4_100.bin

reset   : Causes a target to cycle from enabled to disabled and back to enabled.

set     : Used to set a property or set of properties to a specific value.
start   : Used to cause a target to change state to a higher run level.
stop    : Used to cause a target to change state to a lower run level.
cd      : Used to set the current default target.
   Example: cd targetname
date    : Used to get the current date.
time    : Used to get the current time.
exit    : Used to terminate the CLP session.
version : Used to query the version of the CLP implementation or other CLP elements.

oemhp_ping    : Used to determine if an IP address is reachable.
Example : oemhp_ping 192.168.1.1

oemhp_loadSSHKey    : Used to authorize a SSH Key File from an URL.
Example : oemhp_loadSSHKey -source http://user:[email protected]/images/SSHkey1.pub
oemhp_deleteSSHKey    : Used to remove a SSH Key associated with a user
Example : oemhp_deleteSSHKey 

HPE CLI Commands:

POWER    : Control server power.
UID      : Control Unit-ID light.
ONETIMEBOOT: Access One-Time Boot setting.
NMI      : Generate an NMI.
VM       : Virtual media commands.
