HP StorageWorks EVA iSCSI Connectivity Option 3.
Description The EVA iSCSI Connectivity Option provides iSCSI connectivity to EVA Fibre Channel storage systems. You may order product AE324A with an EVA storage system or to upgrade an existing EVA storage system. This option includes one hardware unit and the components needed to install in any EVA cabinet.
Prerequisites • EVA4000/6000/8000 (XCS 6.000, 5.100, 5.031) • EVA3000/5000 (VCS 4.001, 3.028) • HP StorageWorks Command View EVA 5.0 Installation instructions For information about installing these products, see the HP StorageWorks EVA iSCSI connectivity quick start instructions for Windows and the HP StorageWorks EVA iSCSI connectivity user guide available at http://h18006.www1.hp.com/products/storageworks/evaiscsiconnect/index.
DHCP assigned IP address of mpx100’s management port may confuse Command View EVA When an mpx100 management port’s IP address is configured using DHCP, Command View EVA initially discovers the mpx100. However, Command View EVA doesn’t rediscover the management port IP address of the mpx100 when another new IP address is assigned by DHCP. Workaround When you configure an mpx100 management port, only select the static IP address option.
When a path is lost to a target, Windows MPIO initiator does not re-log in to the target after the path becomes available Microsoft MPIO 2.0 does not have any polling functionality to query the target when it becomes available. The Target status is inactive and the total path count is reduced until the initiator re-logs in to the target manually. Workaround 1. 2. 3. 4. 5. Start the mpx100 Manager GUI. Select the Inactive target under the Targets tab. Click Log On. Click the Enable multi-path check box.
• A date code, in yyyy-mm format followed by another dot (.) • A reverse domain name • Optional colon (:) prefixed by a string If only using ASCII characters (U+0000 to U+007F), the following characters are allowed: • • • • • ASCII ASCII ASCII ASCII ASCII dash character (’-’ = U+002d) dot character (’.’ = U+002e) colon character (’:’ = U+003a) lower-case characters (’a’..’z’ = U+0061..U+007a) digit characters (’0’..’9’ = U+0030..U+0039) NOTE: See section 3.2.
Workaround Make the change to the registry, or cut and paste the following lines to a text file named tcp1323opts.reg. tcp1323opts.reg. : REGEDIT4 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters] "Tcp1323Opts"=dword:00000002 Double-click the file to add changes to the registry for the iSCSI initiator. CAUTION: Using the Registry Editor incorrectly can cause serious problems that can require reinstallation of the operating system. Back up the registry before making any changes.
Command View iSCSI host objects Fibre Channel ports are not updated during mpx100 FRU replacement Command View presents LUNs to the mpx100 Fibre Channel port WWPNs through the the iSCSI host entry in the Command View EVA hosts folder. If an mpx100 is replaced, the iSCSI host entry must contain the WWPNs of the replacement to continue LUN presentation. Workaround If the replaced mpx100 loses communication after restoring the configuration file, update the iSCSI controller object WWN as follows: 1.
Rebooting the mpx100 to activate a new firmware version may result in a lost connection between a single-path iSCSI initiator and the mpx100 iSCSI port Although the average mpx100 reboot time is under 50 seconds, the reboot can result in a lost connection between a single-path iSCSI initiator and the mpx100 iSCSI port.
Supersedes history Supersedes mpx100 firmware version 2.0.5.1. EVA iSCSI Connectivity Option 3.0 is recommended for all mpx100 models. Effective date October 2006 EVA iSCSI Connectivity Option 3.
