Chapter 5. Completing setup This chapter gives the details for setting up the NAS 200 so clients and servers on your network can access the storage. v If Windows clients and servers will access your storage, follow the steps in “Defining Windows users and groups”. v If UNIX and UNIX-based clients and servers will access your storage, follow the steps in “Defining UNIX users and groups” on page 28.
6. Click OK. The new group name should appear in the list of group names. 7. Repeat Steps 1 on page 27 through 6 for each new local group you wish to add. If your storage is also going to be accessed by UNIX or UNIX-based clients and servers, continue with “Defining UNIX users and groups”. Otherwise, continue with “Creating shares” on page 32. Giving storage access to Windows domain users and groups You must first join the NAS 200 to the Windows domain.
If you are going to define a local UNIX name space, continue with “Using a local UNIX name space”. If you are going to use a UNIX name space defined on a NIS domain, continue with “Using the UNIX name space on an NIS domain” on page 31. Using a local UNIX name space This procedure should only have to be performed once. You may have to add more groups and users in the Server for PCNFS page if you add more users and groups to your UNIX environment and NAS 200 or Windows domain at a later time. 1.
15. In the Group file path and name field, enter c:\winnt\system32\drivers\etc\group, then click Apply. 16. Click Maps. 17. On the Maps page, you can configure simple maps or advanced maps. Configure simple maps if the Windows user name and UNIX user name is the same for each UNIX user to be mapped, and the Windows group name and UNIX group name is the same for each UNIX group to be mapped. Otherwise, you should configure advanced maps.
7) Click Add to add the mapping between the UNIX group name and Windows group name to the list of maps. 8) If multiple Windows group names are mapped to one UNIX group name, you must select one Windows group name to be the primary group name. Select the mapping corresponding to the primary group name from the list of maps, and then click Set Primary. 20. Click Apply. You may now continue with “Creating shares” on page 32.
6) Enter a Windows user name, or select one from the list of Windows user names. 7) Enter a UNIX user name to be mapped to the Windows user name you specified, or select one from the list of UNIX user names. 8) Click Add to add the mapping between the UNIX user name and Windows user name to the list of maps. 9) If multiple Windows user names are mapped to one UNIX user name, you must select one Windows user name to be the primary user name.
v Windows clients and servers, then click CIFS Sharing and specify access permissions as desired. (Note that by default, every user has full access to all files and directories under the shared folder.) v UNIX clients and servers, then click NFS Sharing and specify access permissions as desired. (Note that by default, every user has full access to all files and directories under the shared folder.) 9. Click OK. The new share should appear in the list of shares. 10.

Chapter 6. Additional administrative functions This chapter describes the additional administrative functions that you can do on the NAS 200.
2. 3. 4. 5. 6. 7. 8. 9. 10. v If you are restoring a backup that you created using Persistent Images in the NAS Backup Assistant, the NT Backup file (*.BKF) was created for the persistent image virtual drive letter instead of the original drive letter. For example, if you selected drive C for backup, a persistent image was created on the next available drive letter in the system, and that drive was backed up instead of drive C.
persistent images as one-time events or regularly repeated events.
Persistent Images This panel lists all of the persistent images that exist on all volumes. On this panel you can: v Create a new persistent image immediately (without scheduling it via the Schedules panel). v Delete an existing persistent image. v Modify properties of an existing persistent image, including read-only or read-write, and retention value.
Schedules Use this panel to schedule persistent images to be taken at specific times (this is independent of the scheduled backup function via NAS Backup Assistant described earlier). Each PSM schedule entry defines a set of persistent images to be taken starting at a specified time and at a specified interval, with each image having the set of properties defined in the entry. This allows you to customize scheduled persistent images on a per-volume basis.
the Recovery Enablement Diskette and Recovery CD Set” on page 77 to restore the NAS 200 to its original (factory) configuration. Backing up the system drive On the Disaster Recovery panel you will find status information for backup operations, both scheduled and immediate, as well as buttons for starting and stopping a backup operation, for configuring backup, and for creating a recovery diskette. Click the Modify Settings button to open the Disaster Recovery Settings page.
then you must configure the recovery diskette so that it will use a static IP address and subnet mask when accessing the network. On the recovery diskette, edit the file a:\net_sets.bat. Near the top of this file are two lines that begin with rem (comment lines) that, when you uncomment them, set the IPAddress and SubnetMask environment variables. Change these lines as follows: 1. Uncomment both lines by removing rem from the beginning of both lines. 2.
2. Insert the recovery diskette in the diskette drive of the NAS 200, and restart the NAS 200. 3. The recovery process begins. The recovery diskette software will locate the first backup image it can find, based on the backup locations specified on the Disaster Recovery Settings panel in Microsoft Windows 2000 for NAS when the diskette was created. Once it has located a backup image it will begin restoring the system drive from the image.
Note: The share settings are maintained in a persistent image. Therefore, granting access to all end-users only permits those users to access files and directories within the persistent image that they would have been able to access originally on the actual drive. PSM notes 1. As mentioned, you can take and keep a maximum of 250 persistent images. These can be taken on local drives, or drives on the external storage that are logically local.
v Once the cache file usage exceeds the automatic deletion threshold (also configured in the PSM Volumes panel for the drive; the default value is 90 percent), PSM automatically selects a persistent image on the volume and deletes it to reduce the cache file usage. It selects the persistent image with the lowest retention value (as described above in the Persistent Images panel section).
Load balancing In load balancing mode, all adapters in the team are active, increasing the total transmission throughput over the common IP subnetwork. If any adapter in the team fails (link failure or complete failure), the other adapters in the team continue to share the network transmission load, although total throughput is decreased. Load balancing is only supported for adapter teams consisting of only one type of adapter; different types of adapters cannot be combined in a load balancing team.
Fast Etherchannel (FEC) is a proprietary technology developed by Cisco. With FEC, you can create a team of two to four ports on the Quad-port 10/100 Ethernet PCI Adapter in to increase transmission and reception throughput. This feature may also be referred to as load balancing, port aggregation, or trunking. When you configure this feature, the adapter ports comprising the FEC team or group create a single high-speed, fault-tolerant link between the engine and the Ethernet switch sharing one IP address.
Chapter 7. Troubleshooting This chapter provides basic troubleshooting information to help you resolve some common problems that might occur with your NAS 200. The chapter is divided into: v “Engine troubleshooting and diagnostics” v “Adapter troubleshooting and diagnostics” on page 62 If you cannot locate and correct the problem using the information in this section, refer to “Appendix B. Getting help, service, and information” on page 83 for more information.
Identifying problems using LEDs The LEDs are part of the light-path diagnostics built into the NAS 200 engine. The LEDs help you identify the type of system error that occurred. See the following sections for more information. Power-supply LEDs The AC and DC power LEDs on the power supply provide status information about the power supply. Table 3 on page 49 describes the AC and DC power LEDs.

Watch the screen for any POST errors. Check the System Event/Error Log for any listed problems. If the system powers up with no errors: a.
Light-path diagnostics You can use the light-path diagnostics built into the NAS 200 engine to identify the type of system error that occurred. Any LEDs that are illuminated remain illuminated during a shutdown as long as the AC power source is good and the power supplies can supply +5V DC current to the NAS 200 engine. This feature helps you isolate the problem, if an error causes the NAS 200 to shut down. See “Light-path diagnostics”.
Table 4. Descriptions of light-path diagnostics LEDs LED Meaning PS1 Power supply 1 failure PS2 Power supply 2 failure PS3 Power supply 3 failure NON Non-redundant power OVER The system has exceeded the power capabilities of the installed power supplies NMI Non-maskable-interrupt occurred TEMP System temperature exceeded maximum rating FAN A fan failed or is operating slowly MEM Memory failure.

Power problems Power problems can be difficult to troubleshoot. For example, a short circuit can exist anywhere on any of the power distribution busses. Usually a short circuit causes the power subsystem to shut down because of an overcurrent condition. Table 6 lists the power error messages that you might encounter. A general procedure for troubleshooting power problems is as follows: 1. Power off the system and disconnect the AC cord(s). 2. Check for loose cables in the power subsystem.
