Check Before Configuration

Check Before Configuration

Check the software installation and initial configuration to ensure that site requirements are met.

Checking Licenses

Log in to DeviceManager. Check whether licenses have been imported and contain the same basic or value-added features as you purchased.

  • If licenses are not imported, import them by following instructions in "Initializing the Storage System" in the installation guide.
  • If the licenses are different from those you purchased, contact Huawei technical support.

Checking Software Installation

Check whether the required software is properly installed on the storage system and application server.

Table 4-1 lists the check items and provides the check methods.

Table 4-1 Software installation checklist

Check Item

Description

(Optional) iSCSI initiator

NOTE:

iSCSI initiators are required only for iSCSI connection.

  • Windows

    On the Windows task bar, check whether Microsoft iSCSI Initiator exists in the All programs list.

  • SUSE

    On a SUSE application server, run the rpm -qa |grep iscsi command. If the iSCSI initiator information is displayed, an iSCSI initiator is installed on the application server.

  • Red Hat

    On a Red Hat application server, run the rpm -qa | grep iscsi command. If the iSCSI initiator information is displayed, an iSCSI initiator is installed on the application server.

  • Solaris

    On a Solaris application server, run the pkginfo | grep iscsi command. If the iSCSI initiator information is displayed, an iSCSI initiator is installed on the application server.

  • HP-UX

    On an HP-UX application server, run the swlist iSCSI-00 command. If the iSCSI initiator information is displayed, an iSCSI initiator is installed on the application server.

  • VMware

    For VMware ESXi 4.1 and earlier versions, an iSCSI adapter already exists in a storage adapter. You can directly enable the iSCSI adapter. For VMware ESXi 5.0 and later versions, you must add an iSCSI adapter on the Storage Adapters page and then perform the follow-up configuration.

For details about installing an iSCSI initiator, refer to "Configuring Connectivity" in Huawei SAN Storage Host Connectivity Guide for XXX. XXX represents a specific operating system, for example, Windows.

NOTE:
  • You can log in to Huawei's technical support website (https://support.huawei.com/enterprise/) and enter the product model + document name in the search box to search for, browse, and download a document.
  • You can use the same method to search for and download other Huawei documents referenced in this document.

(Optional) UltraPath

NOTE:
  • Multipathing software is required when redundant paths exist between the storage system and the application server.
  • UltraPath is Huawei-developed multipathing software.

For details about installing UltraPath, refer to the OceanStor UltraPath for XXX User Guide. XXX represents a specific operating system, for example, Windows.

NOTE:

You can log in to Huawei's technical support website (https://support.huawei.com/enterprise/) and enter UltraPath in the search box. Then, select a path from the paths that are automatically displayed to go to the document page. Search for, browse, and download desired documents. To download UltraPath software, click the Software Download tab, and search for and download UltraPath software specific to your product version.

Checking Network Connection Status

Table 4-2 lists the check items and provides the check methods.

Check Item

Check Method

Connection between a maintenance terminal and a storage system

Check whether the management network port on the storage system communicates with the maintenance terminal properly.

In CLI mode of the maintenance terminal, run the following command:

  • For IPv4, ping ip (where ip indicates the IP address of the management network port).
  • For IPv6, ping -6 ip (where ip indicates the IP address of the management network port).

If the maintenance terminal receives data packets from the management network port, the storage system and maintenance terminal communicate properly. If the maintenance terminal receives no data packets from the management network port, change the IP address of the management network port and try again.

Connection between a storage system and an application server (using a Windows application server as an example)

When an iSCSI front-end port on the storage system is used for connection, check whether the iSCSI front-end port communicates with the service network port on the application server properly.

In CLI mode of the application server, run the following command:

  • For IPv4, ping ip (where ip indicates the IP address of the iSCSI front-end port).
  • For IPv6, ping -6 ip (where ip indicates the IP address of the iSCSI front-end port).

If the application server receives data packets from the iSCSI front-end port, the storage system and application server communicate properly. If the application server receives no data packets from the iSCSI front-end port, replace the network cable, change the IP address of the iSCSI front-end port, or add a route between the iSCSI front-end port and service network port, and try again. For details about how to change the IP address of an iSCSI front-end port or add a route between an iSCSI front-end port and a service network port, see the DeviceManager online help.

When a Fibre Channel front-end port on the storage system is used for connection, check whether the rate of the Fibre Channel front-end port is the same as that of the Fibre Channel bus adapter (HBA) on the application server.

If the rates are different, change the rate of the Fibre Channel front-end port. For details about how to change the rate of a Fibre Channel front-end port, see the DeviceManager online help.

When a Fibre Channel front-end port on the storage system is used for connection, check whether the mode of the Fibre Channel front-end port is the same as that of the Fibre Channel HBA on the application server.

If the modes are different, change the mode of the Fibre Channel front-end port. For details about how to change the mode of a Fibre Channel front-end port, see the DeviceManager online help.
