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 22).

Setting Up the Ports for an iSCSI Connection

To establish an iSCSI connection between the HP 3PAR StoreServ Storage and the ESX host, 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. The HP 3PAR StoreServ 10000 Storage and the HP 3PAR StoreServ 7000 Storage support

a 10 Gb iSCSI connection and require a one-time configuration using the controlport

command.

Use 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 Label Partner FailoverState

0:2:1 target offline - 2C27D754521E iscsi iSCSI - - -

0:2:2 target offline - 2C27D754521A iscsi iSCSI - - -

# 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 reconfigure, 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 Label Partner FailoverState

0:2:1 target ready - 2C27D754521E iscsi iSCSI - - -

0:2:2 target ready - 2C27D754521A 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

3. Use the HP 3PAR OS CLI showport -iscsi command to check the current settings of the

iSCSI ports:

# showport -iscsi
