file is configured properly.
1. Open the /etc/hosts file.
NOTE: The following is an example:
127.0.0.1 localhost.localdomain localhost matrix
2. If the hostname of the system is identified on the line
with 127.0.0.1, you must create a new host line.
3. Remove the hostname from the 127.0.0.1 line.
NOTE: The following is an example:
127.0.0.1 localhost.localdomain localhost
4. On a new line, type the IP address of the system.
5. Using the Tab key, tab to the second column and enter the
fully qualified hostname.
6. Using the Tab key, tab to the third column and enter the
nickname for the system.
NOTE: The following is an example of a completed line:
1.1.1.1 matrix.localdomain matrix
where 1.1.1.1 is the IP address of the server and
matrix is the hostname of the server.
7. Restart the server for the changes to take effect.
4.8 VMware
- If you are unable to connect to VMware ESX Server from a
remote ASM GUI, even though it appears in the Enterprise
View as a remote system, most likely, some required ports
are open and others are not. (The VMware ESX firewall blocks
most ports, by default.) Check to make sure that all ports
34570 thru 34581 are opened on the ESX server.
- After making array configuration changes in VMware, you must
run the "esxcfg-rescan" tool manually at the VMware console
to notify the operating system of the new target characteristics
and/or availability. Alternatively, you can rescan from the
Virtual Infrastructure Client: click on the host in the left
panel, select the Configuration tab, choose "Storage Adapters",
then, on the right side of the screen, click "Rescan".
- With VMware ESX 4.1, the OS command 'esxcfg-scsidevs -a'
incorrectly identifies the Adaptec ASR-5445 controller as
"Adaptec ASR5800". (ASM itself identifies the controller
correctly.) To verify the controller name at the OS level,
use this command to check the /proc file system:
# cat /proc/scsi/aacraid/<Node #>
where <Node #> is 1, 2, 3 etc.

5. RAID Level-Specific Notes
5.1 RAID 1 and RAID 5 Notes
- During a logical device migration from RAID 1 or RAID 5 to
RAID 0, if the original logical drive had a spare drive
attached, the resulting RAID 0 retains the spare drive.
Since RAID 0 is not redundant, you can remove the hot spare.
