HP LeftHand SAN Solutions Support Document - Application Notes - QLogic HBAs and the LeftHand SAN 20071223

• Disk Management is used to write a disk signature, create a Basic type of

disk, partition and format the volume. Dynamic disks were not tested and

are not supported with the Microsoft iSCSI Initiator.

• For LeftHand iSCSI volumes which are grown in size, the Microsoft

DISKPART utility may be used to increase the volume size and therefore

make this new space available to the partition in the operating system.

(See Microsoft KB #300415 and/or the LeftHand SAN User’s Guide

pages 353-355).

• Configuration of CHAP (1 or 2-way) is configured for the target in the

LeftHand CMC during definition of the Initiator’s Authentication Group.

Configuration of the initiator may be performed in SANsurfer or the

Microsoft iSCSI applet. Our testing found no difference in configuration of

these settings and recommends the Microsoft iSCSI applet for configuring

CHAP. Under the “Targets” tab, select the target, “Log On,” and

“Advanced.” Select “CHAP Logon Information,” enter the Username and

Target Secret to match configuration in the CMC and select “Mutual

CHAP” for 2-way.

• Windows SANsurfer requires that the password not be blank. Consult the

SANsurfer readme for additional requirements. SANsurfer requires DNS

name resolution either manual or as defined in the operating system.

To change the host IP name resolution table, edit the

%systemroot%\system32\drivers\etc\hosts file

RedHat Enterprise Linux v5.x & Novell SUSE Linux Enterprise Server

v10 SP1

Run the ql-iscsi-install script. The installation log will be saved in the /usr/src/

qlogic directory. (ql-iscsiinstall<driver version>.log. During the installation

script, it will build, install and load the module. The driver performs device

discovery by default. Command line parameters may be specified to override

default device driver settings. (./ql-iscsi-install –o ql4xmaxdepthq=32)

SANsurfer requires that the username specified be an account in both the

adm and root groups on the system in which the agent is running. Before

changing the password, consult the SANsurfer readme for important

requirements, including additional package requirements. SANsurfer

requires DNS name resolution either manual or as defined in the operating

system. To change the host IP name resolution table, edit the /etc/hosts file.
