IBM MegaRAID BIOS Config Utility RAID-10 Configuration

with 13 comments

So, a lot of people have difficulties configuring RAID-10 using MegaRAID because if you have for example four hard disks and you add them to a Disk Group, the only available options are RAID-0 and RAID-1.
Here is how to do this on an IBM System x3650 server with four 300GB SAS hard disks.

During the system boot you will be given the following options.



You will select the “Diagnostics” (in this case using F2 key) and when MegaRAID is loaded you can use “Ctrl+H” key combination to enter the WebBIOS configuration utility.



From the above capture you can also see that there is no virtual disk configured and the controller detected four JBOD disks.
When you enter the utility, you will have the ability to select the adapter you want to configure. In our case we only have one adapter so it is very straightforward.



Next, we have the MegaRAID BIOS configuration main menu for the selected adapter.



From the main menu you select option “Configuration Wizard” and you will get the following screen.



From the above configuration types, we select “New Configuration” since there is no prior configuration. This can also be used if you want to replace the existing configuration with a new one. Before proceeding you will get a warning that this selection will erase the current configuration as shown below.



Next, you select the hard disk drives you want to add to the RAID array. To select more than one press CTRL key. In our case all four disks will be selected in order to implement the RAID-10 level.



In the next window you will have to select “Manual Configuration” if you want to create a RAID-10 array.



Below you select (once again using CTRL key) the first two disks and click “Add To Array” in order to add them to the “Drive Group0″ on the right side panel.



After adding the first two disks you click on “Accept DG” to complete the setup of this drive group and create a new one.



Follow the same procedure and add the other two disks to the new drive group and then click “Accept DG” and “Next” to continue.



You add the two newly created arrays to a span by selecting each one of them and then clicking on “Add to SPAN”.



And as you can see below, the selected RAID level is 10. Here you can tune your RAID-10 configuration and when you are ready you click on “Update Size” and then “Accept” button.



Finally, you can continue by hitting “Next” and after the usual warning messages and final review of the configration, the RAID will start initializing.



On the bottom right you have some additional options that you can use but in any case, when the initialization process is completed the RAID-10 virtual disk will be ready to use.

IBM RSA-II Card Replacement and Re-configuration

with 2 comments

Although I don’t like IBM’s RSA-II technology, I recently came across a fucked up IBM x3850 server that I had to replace its RSA-II card among other hardware.

This card is installed on the I/O board that you see in the following diagram (this was taken from IBM’s manual for this specific model).



Before replacing the card, the IBM engineer that did the replacement resetted the RSA-II’s settings by pressing the button you see highlighted in the picture below.



Now, after booting the server I attempted to upgrade the RSA-II firmware to the latest version but I came accross the following error…

[root@somewhere ~]# ./ibm_fw_rsa2_zuep66a_linux_i386.sh -s

Could not find RSA or RSA-II driver.  Please check your RSA or RSA-II driver
installation
Error flashing RSA2 firmware: 171
[root@somewhere ~]#

The solution was to first update the server’s BMC. So…

[root@somewhere ~]# ./ibm_fw_bmc_z2bt05j_linux_i386.sh -s -a
64 bit detected

Next, install and start the ‘ibmasm’ daemon that will provide you access to the IBM ASM from user space.
And at last, you can proceed to the RSA-II firmware upgrade…

[root@somewhere ~]# ./ibm_fw_rsa2_zuep66a_linux_i386.sh -s

Finally, in order to make the RSA-II accessible via network, install the IBM Advanced Settings Utility (IBM ASU) and initialize the network configuration using the following commands.

# Initilize network on RSA-II interface
asu set RSA_Network1 Enabled
# Set the IP address
asu set RSA_HostIPAddress1 XXX.XXX.XXX.XXX 
# Set the Subnet Mask
asu set RSA_HostIPSubnet1 255.255.255.0.
# Set the Default Gateway
asu set RSA_GatewayIPAddress1 XXX.XXX.XXX.XXX.

Hopefully, you will be able to connect to the web interface of the RSA-II and prompted for username and password.



The default credentials are:
Username: USERID
Password: PASSW0RD
Notice that the password is written with a zero (0) instead of the letter ‘O’.



And as you can see, there is no error detected so we are probably all done.
