Product description When you power up the storage system, each SP boots and executes FLARE OE software. Shared storage control Shared storage control software allows only the server(s) assigned to a virtual disk to access the virtual disk. Navisphere Express EMC Navisphere Express is a storage-system-based management utility for configuring and managing AX4-5 series storage systems.
Product description Navisphere Storage System Initialization Utility The EMC Navisphere Storage System Initialization Utility runs on your management station or attached server. It discovers uninitialized AX4-5 series storage systems, lets you assign IP addresses to the SPs on the same subnet, assign IPs to iSCSI ports for AX4-5i and AX4-5SCI storage systems, and set up security for these storage systems.
New features and changes New features and changes Increased support for Fibre Channel I/O FLARE version 02.23.050.5.707 adds support for AX4-5F8 and AX4-5SCF4, which provide four Fibre Channel ports per storage processor. If you are managing an AX4-5F8 or AX4-5SCF4 storage system, host initiator records will be propagated to all ports on storage processor A and storage processor B.

Technical notes Technical notes This section contains information that will help with the installation, use, and management of the storage system. It provides generic information that applies to all platforms, as well as platform-specific information. Navisphere CLI Navisphere CLI is no longer supported on the AX4-5 series storage systems. Navisphere Secure CLI should be used instead.
Technical notes Notes: This procedure may take 30-60 minutes to complete. During this procedure, you may see some temporary alerts including 0x7428, 0x743a, 0x720f, 0x7403 or 0x7404. After the upgrade completes, all alerts will eventually disappear. An optional second SPS can be added after Step 7. The single SP will not use the SPS so the second SPS is always new when the second SP comes up.
Technical notes Disk module insertion and removal When inserting or removing more than one disk module from a storage system, you must pause between each removal and insertion to allow the storage system to recover. Before inserting or removing the next disk module you should make sure that: A newly inserted disk module's amber light is off and its blue light has returned to a normal state: on or blinking due to I/O in progress.
Technical notes Linux server notes Snapshot management The reboot of the Linux server may be slow if deactivated snapshots exist. Activating the snapshots allows the reboot to complete normally. VMware ESX Server configuration and usage notes See the notes in the “Installation” section.
Documentation Documentation The AX4-5 support website where you accessed these release notes also contains the most up-to-date documents and troubleshooting trees. The AX4-5 Series Documentation CD (P/N 053-001-992) that shipped with the storage system also contains documents and troubleshooting trees for this product; however, they are superceded by those on the AX4-5 support website. The troubleshooting trees on the AX4-5 support website are updated frequently.
Documentation Update to AX4-5 Series - Installing an iSCSI Storage System with a Network Connection to a Windows Server and AX4-5 Series - Installing an iSCSI Storage System with a Direct Connection to a Windows Server Dynamic disks Contrary to what the installation guides say, do not upgrade a disk in an iSCSI storage system to a dynamic disk when writing a digital signature to the disk. Dynamic disks are not supported by the Microsoft iSCSI Software Initiator.

Installation Skip the step on installing software enablers because they are not needed for Navisphere Express. Use Navisphere Express to configure the storage system as follows: 1. Create a hot spare. 2. Create one or more disk pools. 3. Create one or more virtual disks on the disk pools. 4. Assign one or more disks to the ESX Server. Use Navisphere Express to set up Event Notification.
Troubleshooting and getting help Troubleshooting and getting help To troubleshoot problems with your AX4-5SC, AX4-5SCi, AX4-5, AX4-5i, AX4-5F8 or AX4-5SCF4 storage system, use the troubleshooting trees in the “Troubleshoot” section on the AX4-5 support website or the AX4-5 Series Documentation CD. You must use the troubleshooting trees before your service provider will send you a replacement part. To launch the troubleshooting trees, click the Interactive help tool in the “Troubleshoot” section.
