3 Configuring the HP 3PAR StoreServ Storage for iSCSI

This chapter explains how to establish an iSCSI connection between the HP 3PAR StoreServ Storage

and the VMware ESX host. If you are running specific CNA cards, a software or hardware iSCSI

initiator can be used. For details about hardware iSCSI configuration, see “Hardware iSCSI

Support” (page 25).

Setting Up the Ports for an iSCSI Connection

To establish an iSCSI connection between the HP 3PAR StoreServ Storage and the ESX host, you

need to set up each HP 3PAR StoreServ Storage iSCSI target port that will be connected to an

iSCSI initiator as described in the following steps.

1. A 10 Gb iSCSI connection, which is supported in the HP 3PAR StoreServ 10000 Storage and

the HP 3PAR StoreServ 7000 Storage, requires a one-time configuration using the

controlport command.

Issue the showport and showport -i commands to check the current CNA configuration.

For example:

# showport

N:S:P Mode State ----Node_WWN---- -Port_WWN/HW_Addr- Type Protocol

0:1:1 suspended config_wait - - cna -

1:1:1 suspended config_wait - - cna -

# showport -i

N:S:P Brand Model Rev Firmware Serial HWType

0:1:1 QLOGIC QLE8242 58 0.0.0.0 PCGLT0ARC1K3SK CNA

1:1:1 QLOGIC QLE8242 58 0.0.0.0 PCGLT0ARC1K3SK CNA

2. If State=config_wait or Firmware=0.0.0.0, use the controlport config iscsi

<n:s:p> command to configure, and then use the showport and showport -i commands

to verify the configuration setting.

For example:

# controlport config iscsi 0:1:1

# controlport config iscsi 1:1:1

# showport

N:S:P Mode State ----Node_WWN---- -Port_WWN/HW_Addr- Type Protocol

...

0:1:1 target ready - 2C27D7521F3E iscsi iSCSI

...

1:1:1 target ready - 2C27D7521F3A iscsi iSCSI

# showport -i

...

N:S:P Brand Model Rev Firmware Serial HWType

...

0:1:1 QLOGIC QLE8242 58 4.8.76.48015 PCGLT0ARC1K3SK CNA

1:1:1 QLOGIC QLE8242 58 4.8.76.48015 PCGLT0ARC1K3SK CNA
