IBM STORAGE LUN SETUP:

                       IBM LUN setup is done using IBM Storage Manager Client or command line tools. Since most of our storage is mirrored the identical LUN has to be created on the both arrays. Storage Manager Client scripting allows easy duplication of identical setup on each array.

Code snippets

Creating host on IBM DS4000 storage system

Create a host entry on with proper host type (LINUX/WINDOWS)(more or less OS type).

create host userLabel="server" hostType=number;

create hostPort userLabel="server-p0" host="server" identifier="210000e0xxxxxxxx" interfaceType=interface; 

Example

create host userLabel="DBZones3" hostType=8;

create hostPort userLabel="DBZones3-p0" host="DBZones3" identifier="210000e08b9a2466" interfaceType=FC;

create hostPort userLabel="DBZones3-p1" host="DBZones3" identifier="210100e08bba2466" interfaceType=FC;

Creating logical drive (LUN) on IBM DS4000 storage system

create logicaldrive array="Array Name" userlabel="LUN name" capacity=X GB owner=(a|b) usagehint=filesystem;

Example

create logicaldrive array="SATA-Array3" userlabel="DBZones3_1" capacity=150 GB owner=a usagehint=filesystem;

create logicaldrive array="SATA-Array2" userlabel="DBZones3_2" capacity=150 GB owner=b usagehint=filesystem;

create logicaldrive array="SATA-Array1" userlabel="DBZones3_3" capacity=150 GB owner=a usagehint=filesystem;

Assigning the logical drive (LUN) to host on IBM DS4000 storage system

set logicalDrive ["LUN Name"] logicalUnitNumber=number host="server";

Example

set logicalDrive ["DBZones3_1"] logicalUnitNumber=0 host="DBZones3";

set logicalDrive ["DBZones3_2"] logicalUnitNumber=1 host="DBZones3";

set logicalDrive ["DBZones3_3"] logicalUnitNumber=2 host="DBZones3";
