Chapter 11 Configuring iSCSI Adapters and Storage5 Specify the outgoing CHAP name.Make sure that the name you specify matches the name configured on the storage side.• To set the CHAP name to the iSCSI adapter name, select Use initiator name.• To set the CHAP name to anything other than the iSCSI initiator name, deselect Use initiator nameand type a name in the Name text box.6 Enter an outgoing CHAP secret to be used as part of authentication. Use the same secret that you enteron the storage side.7 If configuring bi-directional CHAP, specify incoming CHAP credentials.Make sure to use different secrets for the outgoing and incoming CHAP.8 Click OK.9 Rescan the iSCSI adapter.If you change the CHAP parameters, they are used for new iSCSI sessions. For existing sessions, newsettings are not used until you log out and login again.Disable CHAPYou can disable CHAP if your storage system does not require it.If you disable CHAP on a system that requires CHAP authentication, existing iSCSI sessions remain activeuntil you reboot your host, end the session through the command line, or the storage system forces a logout.After the session ends, you can no longer connect to targets that require CHAP.Required privilege: Host.Configuration.Storage Partition ConfigurationProcedure1 Open the CHAP Credentials dialog box.2 For software and dependent hardware iSCSI adapters, to disable just the mutual CHAP and leave theone-way CHAP, select Do not use CHAP in the Mutual CHAP area.3 To disable one-way CHAP, select Do not use CHAP in the CHAP area.The mutual CHAP, if set up, automatically turns to Do not use CHAP when you disable the one-wayCHAP.4 Click OK.Configuring Advanced Parameters for iSCSIYou might need to configure additional parameters for your iSCSI initiators. For example, some iSCSIstorage systems require ARP (Address Resolution Protocol) redirection to move iSCSI traffic dynamicallyfrom one port to another. In this case, you must activate ARP redirection on your host.The following table lists advanced iSCSI parameters that you can configure using the vSphere Web Client.In addition, you can use the vSphere CLI commands to configure some of the advanced parameters. Forinformation, see the Getting Started with vSphere Command-Line Interfaces documentation.IMPORTANT Do not make any changes to the advanced iSCSI settings unless you are directed by VMwaresupport or Storage Vendors.VMware, Inc. 95
