SUN E450 with Solaris 8

[copperslim]

I am adding 3X 36Gb (x5242A) of disks to my E450.
It has 3 controllers and only 2 of the controllers are used.
The patch level on the system is 108528-03 and the latest patch level is 108528-20.

How to I find out if the disks are HOT PLUG
Do I need to patch server to the latest patch level?

This is how I intend to carry out the work.
shut system down
Insert the three disk into server
2 disks in any of the used controllers
1 disk in the unused controller
boot system (boot -r)
type drvconfig
then type disks
then
ls -lt /dev/dsk |more
check new disk and its logial device name appear at top of list with date and creation.

Please, advice if wrong.

I would advise you to upgrade the patch level of your system.
This can be done by installing Solaris 8 recommended.
Download from

http://www.sun.com.

The system will require rebooting after patching.

The disks can be connected into the system hot.

The command "devfsadm -c disk will configure the new disks without a reboot so that the format command can see the disks. devfsadm replaces drvconfig.

Here are my steps:

1. Download solaris 8 recommended and ./install_cluster
2. reboot the system after patching.
3. Run the format command and record all the present disks.
4. install the new disks
5. run devfsadm -c disks
6. run format and look for the new disks
7. partition and label the new disks
8. newfs the new partitions and then fsck the partitions
9. you are now ready to use the new disks
10. vi /etc/vfstab
make the mountpoints (example: /test , /test1 )
mount -a ( do a df -k and you should see the new mountpoints.


If disk suite or veritas is in use then you must consider
bringing the disks into their environment.

Thanx, that is of great help.
My client do not want me to patch the server.
How do I find out if the server is HOT PLUG?

Are you asking if the disks are hot -plugable? If so the answer is yes. Go to Google and search for "just the facts for the E450 server and look on page 8 and 15 to verify".

Thanx tuka[/blue]. Just the facts for the E450 server gave me all the info I need for E450.
I tried devfsadm -c disks, I had an error. I then tried drvconfig the disk and it worked. Again thanx.
