vSphere Storage Table 14-2. iSCSI SAN Configuration Requirements (Continued) Component Comments Dell EqualLogic Make sure ARP Redirect is enabled on independent hardware iSCSI adapters. HP StorageWorks (formerly LeftHand) Make sure ARP Redirect is enabled on independent hardware iSCSI adapters. ESXi Configuration Set the following Advanced Settings for the ESXi host: Disk.UseLunReset to 1. A multipathing policy of Most Recently Used must be set for all LUNs hosting clustered disks for active-passive arrays. A multipathing policy of Most Recently Used or Fixed may be set for LUNs on active-active arrays. Allow ARP redirection if the storage system supports transparent failover. 132 VMware, Inc.
Managing Storage Devices 15 Manage local and networked storage device that your ESXi host has access to. This chapter includes the following topics: n “Understanding Storage Device Naming,” on page 133 n “Storage Refresh and Rescan Operations,” on page 135 n “Identifying Device Connectivity Problems,” on page 138 Understanding Storage Device Naming Each storage device, or LUN, is identified by several names. Device Identifiers Depending on the type of storage, the ESXi host uses different algorithms and conventions to generate an identifier for each storage device. SCSI INQUIRY identifiers. The host uses the SCSI INQUIRY command to query a storage device and uses the resulting data, in particular the Page 83 information, to generate a unique identifier. Device identifiers that are based on Page 83 are unique across all hosts, persistent, and have one of the following formats: n naa.number n t10.number n eui.number These formats follow the T10 committee standards. See the SCSI-3 documentation on the T10 committee Web site. Path-based identifier. When the device does not provide the Page 83 information, the host generates an mpx.path name, where path represents the path to the device, for example, mpx.vmhba1:C0:T1:L3. This identifier can be used in the same way as the SCSI INQUIRY identifies. Legacy Identifier The mpx. identifier is created for local devices on the assumption that their path names are unique. However, this identifier is neither unique nor persistent and could change after every boot. In addition to the SCSI INQUIRY or mpx. identifiers, for each device, ESXi generates an alternative legacy name. The identifier has the following format: VMware, Inc. 133
