 FRS-8.60 Code autoConfigIp Feature Discussion -  This version of code has the ability to automatically assign IP addresses to STK drives in the SL8500 library.  There were some questions about the syntax of the commands. The discussion below will attempt to clarify some points.

Solution

 From the release notes:

• Added the following commands for users admin, advsrv, remote, service and test to support the auto configuration of drive IP addresses:

• Drive autoConfigIp default <drive address> | *

• Set drive net data (ip address, gateway & subnet) to the drive default values: (STK drives only)

• default IP address: 10.0.0.1

• default Gateway: 10.0.0.254

• default Subnet: 255.255.255.0

Example Syntax: 

Where <drive address> specifies an individual drive as library,rail,column,side,row and <*> is all drives

SL8500> drive autoConfigIp enable  (enables the autoConfig feature)

SL8500> drive autoConfigIp default *  (will set all STK drives in the library  to the default values in the list below)

SL8500> drive autoConfigIp default 1,1,-2,1,1  (will set the single STK drive at the specified location [Bay 64] to the default values in the list below)

default IP address: 10.0.0.1

default Gateway: 10.0.0.254

default Subnet: 255.255.255.0

NOTE: If you want to set unique addresses for all STK drives (SDP connectivity), use the examples below:

Example Syntax to auto configure all STK drives to unique addresses:

SL8500> drive autoConfigIp enable  (enables the autoConfig feature)

SL8500> drive autoConfigIp 172.18.18.11  (will assign IP addresses sequentially to all drives starting at Bay1 = 172.18.18.11 for a SL8500 with a libraryID of 1 and a complexID of 1) 

• Default Base Starting IP address = 172.18.X.Y

• Where X = ((complexId - 1) * 10) + libraryId + 17  (instruction from the help file)

• ((1 - 1) * 10) + 1 + 17    X =18  (calculated value using above formula)

• Where Y = drive bay number (driveId) + 10 (instruction from the help file)

• 1+ 10   Y=11 (calculated value using above formula)

Other commands to change to different default values...

  SL8500>drive autoConfigIp netmask 255.255.255.0      (assuming a standard class C subnet, use appropriate value)

  SL8500>drive autoConfigIp gateway 172.18.18.1      (assuming this is the appropriate value)  

This is for STK drives!   IMPORTANT: The library does NO checking of duplicate IP addresses in a complex with the user defined values!

Below is the help file:

• Added the option to retrieve the network data from all drives, rather than just one drive:

• drive getNetData <drive address> | *

• Added the following commands for users admin, advsrv, remote, service and test to support the auto configuration of drive IP addresses:

• drive autoConfigIp default <drive address> | *

• Set drive net data (ip address, gateway & subnet) to the drive default values: (STK drives only)

• default IP address: 10.0.0.1

• default Gateway: 10.0.0.254

• default Subnet: 255.255.255.0

• drive autoConfigIp enable | disable | print

• Enable or disable or print status of drive auto ip configuration.

• print will display the enable status, as well as the base ip address, gateway and subnet mask.

• Once enabled, drives that fit the criteria will be configured with an ip address. If the default base starting ip address is used, the calculation is as follows:

• Default Base Starting IP address = 172.18.X.Y

• Where X = ((complexId - 1) * 10) + libraryId + 17 complexId ⇐ 23

• Y = drive bay number (driveId) + 10

• Default Base Gateway Address = 172.18.18.1

• Default Base Subnet Mask = 255.255.254.0 (STK drives only)

• drive autoConfigIp ip <IP_address>

• Sets the base IP address to values other than the default (see above) when drive autoConfigIp is enabled.

• The user defined base ip address should be of the form:

• AAA.BBB.CCC.0, where, the 0 will be replaced with Y = driveId + 10

• IMPORTANT: The library does NO checking of duplicate IP addresses in a complex with the user defined values!

• drive autoConfigIp gateway <IP_address>

• Sets the base gateway to a value other than the default (see above) when drive autoConfigIp is enabled.

• drive autoConfigIp netmask <IP_address>

• Sets the base subnet mask to a value other than the default (see above) when drive autoConfigIp is enabled.
