Bro Attach a serial cable to the storage system and connect to a laptop.
Open a terminal emulation program to run a text interface, such as
HyperTerminal* or ProCommPlus*.
Use the following settings to configure your session:
Bits per second = 19200
Data bits = 8
Parity = None
Stop bits = 1
Flow control = None
Backspace key sends = Del
Emulation = ANSI
If using HyperTerminal, set the properties for the backspace key and
emulation after the session is established. If you exit the session and
return to the session in order to use the Configuration Interface, the
screen will not open correctly.
Connect to the FAS250 console by using the provided serial cable.
Logon to the appliance using username 'root' and the root password.
Type the following exactly as shown:
priv set diag
halt -c factory
The filer will reboot and ask for a fresh setup the next time it boots.
This should only be done if you are sure you really want to reset the configuration! This should probably only be done if you know how to then proceed and re-configure the filer.
If you do not have the 'root' password try resetting it. You will have to reboot the filer and type "ctrl-c" when prompted to access the special maintenance boot menu. Then choose the option for resetting the root password.
Run or open the anti-virus software. Then, run the Tune-up Utility of 2008 (from the internet free) to optimize your registry. If this won't do the job, save your important file in another hard drive. Then, you can reformat the hard drive.
You can select Install and you can create a great customizes doc for installation steps.
Generally you can configure AX150 from a web based interface.
Enter the ip addess of the storage processor and a java application will appears.
You should do the following:
1. Create raid groups
2. Create LUNs on raid group
3. Register the hosts
4. Add hosts and LUNs to a storage groups
I don't understand your description. sorry. But if you are switching over from Mirror to stripping then you will surely loose your files. Switching raid configuration will also redo the hard drive relativity and will reformat the drives automatically. If your backup is a server then you need to go to system bios and configure the raid from there. I suggest backup the backups first before you do it. If your backup is an external hard drive then go to its http settings and configure it there. It will surely format your drive.
The first point to note is that this unit does not support more than 1.6TB total disk. (4 x 400GB drives) This is stated in the manual which is on the CD that came with the unit. You cannot configure a mix of RAID1 and Linear (JBOD) drives, so you plan will not work.
What is your connectivity to the SAN? fiber or iSCSI?
Have you checked the management tools to see if there are any errors on the data paths?
If using iSCSI and the SAN and server are in the same network segment, make sure the default gateway is empty for the iSCSI connection.
Look at the routes on the server to make sure the traffic is not leaving the subnet through a router and back to the SAN, and vice versa.
If fiber then you'll have to use the tools given to check for errors.
I'm not an EMC guy, but that error makes me question the connectivity of SP-A to your Management Server. Check the host port status on both controllers to see if they are active. If this is on a SAN, you might check the switch port status going to SP-A.
