File Name: Readme_W2K.txt This README file contains the latest information about installing IBM Netfinity FAStT Storage Manager. Refer to the IBM Support Website for the latest information and updated readme file (See Section 6.1 below). Last Update: 09/08/00 CONTENTS -------- 1.0 Overview 2.0 Change History 3.0 Installation and Setup Instructions 4.0 Configuration Information 5.0 Unattended Mode 6.0 Web Sites and Support Phone Number 7.0 Trademarks and Notices 8.0 Disclaimer 1.0 Overview -------------- 1.1 Overview This IBM Storage Manager release includes the IBM Netfinity FAStT Storage Manager version 7.02 for Windows NT4 and Windows 2000. In addition, it includes the controller 4.00.02 firmware and latest NVSRAM files for IBM machine types 3526/3542/3552. The Windows 2000 directory contains the documentation and files necessary for installing the IBM Netfinity FAStT Storage Manager Software V 7.02 for Windows 2000. 1.2 Limitations 1. Plug-n-Play(PNP)services problem when multiple new disk devices are added. When creating logical drives on the Storage Subsystem with the FAStT Storage Manager, create one logical drive at a time followed by a rescan for hardware changes under the disk drives tree of Windows 2000(W2K) Manage|Devices. The PNP process may take a couple of minutes to clear its procedures so do not create logical drives and rescan quicker than this time period. If multiple new disk devices are added to locations where disk devices have never been seen before on the system where the installation is taking place, or if installing an existing RAID Subsystem, then the W2K PNP process assumes the disk devices are not working properly. This is indicated by a "Yellow Bang" next to the disk device under <>. Pop Up windows may alert the user to new hardware and request that the system be rebooted. Follow the prompts to reboot the system. In some instances a blue-screen error display may occur during the reboot process indicating "DRIVE_POWER_STATE_ FAILURE". In this scenario it may take a few system reboots before the condition clears completely and the system is again fully operational. The number of reboots will depend on the number of new disk devices. 2. No Microsoft Digital Signature on RDAC Driver. When installing the IBM Netfinity FAStT Storage Manager RDAC version 07.02.95.02 for the first time, the following message will appear: "Software Package Unknown" This message is expected and the user should proceed with the installation of IBM Netfinity FAStT Storage Manager RDAC. 3. Additional Steps Required for Uninstalling the RDAC Driver. When Uninstalling the IBM Netfinity FAStT Storage Manager RDAC, version 07.02.95.02, use the following steps. a. Run the uninstall Add/Remove Programs. b. Right-click|uninstall the RDAC Virtual Adapter node in Computer Management|Device Manager|SCSI and RAID Controllers. Note: do not restart when prompted to in this step. c. Manually delete the file \winnt\inf\rdacfltr.pnf. Restarting the system is not necessary. 4. Microsoft Clustering Problem - Cluster loses communication to resources and goes offline. An issue exists with Microsoft Cluster Server running under Windows NT 4.0 and service pack 4, 5 or 6x and Windows 2000. When resources are moved between cluster nodes there is a possibility of file system corruption. (In user systems, resources may need to be moved manually when bringing one node down, or the cluster may automatically move the resource when the node loses contact on redundant paths to the array controllers, or the cluster loses contact with the node.) When the cluster resource is moved, the owning node flushes cache and then releases the reservation to the logical drive(s). The other node then reserves the logical drive(s). In some instances, this causes file system information to be corrected in such a way that some files are no longer accessible. It should be noted that the problem was detected when a 3526 array module and a 3552 array module were part of the same configuration. The problem did not show up in a dual 3526 array module or a dual 3552 array module configuration. 5. Storage Manager prompts for a password if all drives removed from storage subsystem After removing all drives from a storage subsystem (or not powering on drives and only controller), the storage management software will prompt the user for a password when trying to start the software or trying to perform protected operations. Any password entered will fail. Password information is stored on a reserved area of each drive on the storage subsystem. Each drive stores a mirrored copy of the password data. With no drives in the storage subsystem, the storage management software does not find the password data when you attempt password protected operations. Add one of the drives to the storage subsystem and retry the operation. 6. Controller on IBM Fibre Channel switch (2109-S16 and 2109-S8) can initialize as L-Port Controllers connected to an IBM Fibre Channel switch might initialize as an L-Port rather than an F-Port or FL-Port. This causes the controller to be inaccessible to the host. The problem is very intermittent and it may occur as often as 50% of the time the user attempts to repeatedly disconnect and reconnect the Fibre Channel cable between the array controller and the Brocade switch. The controller affected is inaccessible to the host. The user can recover this problem by shutting off the storage subsystem and the switch. Power up the switch first followed by the storage subsystem. The controller will initiate as F-Port or FL-Port and the host will be able to communicate to the storage subsystem. 7. Auto LUN/Array Transfer not supported If a controller fails over arrays to the alternate controller and the failed controller is replaced and brought back online, the arrays do not automatically transfer to the preferred controller. This must be done manually by redistributing arrays. 8. Display issues when using 256 color settings A brownish hash pattern is displayed on the windows and in online help when running in 256 color mode. Run the SM 7 application in a higher display mode. 9. Error message "Service Error 100" after installing SM 7 Host-Agent software Causes of this include: a. Host-agent software does not find any controllers with firmware version 4.x b. Controllers with firmware version 4.x have the access volume disabled with NVSRAM configuration settings c. NVSRAM on controller in a storage subsystem that user is attempting to manage has access volume Logical Unit Number set to a number that is already in use by another logical drive d. NVSRAM on controllers in storage subsystem user is attempting to manage contains an access volume Logical Unit Number that is not supported by the operating systems plus installed patches (for example, the Access Volume is configured as LUN 31, but the operating system and service packs only support 8 LUNs) 10. Windows 2000 does not see non-clustered disks once cluster is installed If a cluster is installed on a system, the user will no longer be able to see non-clustered disks on that system. It appears that a Veritas driver (dmio.sys) that is installed as part of Windows 2000 is preventing them from being seen correctly in disk management. The LUN appears, but no information is available, apparently because the dmio.sys is reporting errors when trying to write to them. Users are restricted from using a system for both cluster and non-clustered storage under Windows 2000. 11. Redundancy check on 3542 can take up to 10 times longer than on other controller platforms A redundancy check (parity scan) uses the VERIFY operation which is not implemented in Hardware on this platform. Parity checking will take a very long time on 3542 based arrays. 1.3 Enhancements N/A 1.4 Prerequisites: - 1.5 Dependencies: IBM Netfinity FAStT Storage Manager V7.02 requires the 3526/3542/3552 controllers to have at least firmware version 04.X. If the user is installing IBM Netfinity FAStT Storage Manager V7.02 (for Windows 2000) onto a host with 3526 controllers that are at firmware 3.X, contact IBM Service for instructions on upgrading the controllers to firmware 4.X. 2.0 Change History -------------------- This is the latest release of IBM Netfinity FAStT Storage Manager for Windows 2000. 2.1 Code levels found in this directory 1.

Support for Vital Product Data 3.0 Installation and Setup Instructions ----------------------------------------- 3.1 Step by step instructions for this code update 1. Install/update the driver for the IBM Netfinity Fibre Channel Host Bus Adapter or the IBM Netfinity FAStT Host Adapter a. Install the Hardware following the instructions that come with the adapter. b. Install the IBM Netfinity Fibre Channel Host Bus Adapter or IBM Netfinity FAStT Host Adapter driver by following the instructions provided in the readme.txt file in the \W2K\Host_Adapter directory on this CD. 2. If upgrading from SM 7.0 or 7.01, uninstall the following existing SM 7 packages: a. IBM Netfinity Fibre Channel SM 7 Client Package b. IBM Netfinity Fibre Channel SM 7 Agent Package c. IBM Netfinity Fibre Channel SM 7 RDAC Package d. IBM Netfinity Fibre Channel SM 7 Migrate Package 3. Install the new SM 7.02 Packages. Refer to the IBM Netfinity FAStT Storage Manager Version 7.02 for Windows 2000 Installation and Support Guide for a list of instructions on installation. 3.2 There is a Host Adapter directory on this CD. Refer to this directory for drivers. Also, refer to the IBM Support Web site for the latest supported host adapters, device drivers, and updated readme. (See Section 6.1) 3.3 Helpful Hints 1. The IBM Netfinity FAStT Storage Manager will prompt the user for a password if an attempt is made to manage a storage subsystem where the Netfinity FAStT RAID Controller Unit does not have access to any drives. This will occur even if no password has been setup. The automatic discovery will discover each storage subsystem as two separate storage subsystems. To prevent this from occurring, ensure that at least one Netfinity FAStT EXP500 Expansion Unit with at least one drive is properly attached to the Netfinity FAStT500 RAID Controller Unit in each storage subsystem being managed. Since the RAID controller unit should not be powered on until the expansion units are attached and powered on, this should be done by powering off the RAID controller unit, properly attaching all expansion units, with drives installed, to the RAID controller unit and powering them on, and then powering the RAID controller unit back on. At this point the storage subsystem(s) can be re-discovered and managed using the FAStT Storage Manager. 2. If you are unable to see the maximum number of drives during "Automatic Configuration", you should be able to use "Manual Configuration" to select individual drives and select the maximum number of drives allowed. 4.0 Configuration Information ------------------------------- 4.1 Include any configuration installation 4.2 Configuration Settings 1.
