Adding disks?

[Packya]

Hi,
We have a solaris 2.6 operating system. Very recently I have been assigned with a job to add a A5000 disk array to the system. The array has 10 disks.

We use a fiber optic cable to connect the array with the system. I have done all that. What is the next step?

Do I reboot the system with a boot -r command? How do I make the system see those disks?

I need some direction. Any help will be vastly appreciated.

Thanks,
P.

ok ... once you have rebooted (-r, or whatever ...) you probably will get the best idea by doing a 'format' command

this will tell you all about your disks and slices, and partitions ...

look at the man pages

to mount these partitions you might want to look in (or alter) the /etc/vfstab

have fun.

If you 'reboot -- -r' and you do not see the disks you may have to modify '/kernel/drv/sd.conf' This depends on the type of Fibre cards you are using.

eg. I'm using JNI (JCOR) fibre cards and had to add the following to sd.conf :

name="sd" parent="fcaw" target=0 lun=0 hba="fcaw0"
name="sd" parent="fcaw" target=0 lun=1 hba="fcaw0"

fcaw = The driver name
fcaw0 = Instance of this driver
Target = t* (c0t*d0)

You should know the lun assignments if you setup the luns using 'rm6'.

Good luck...

Yea, that's pretty much it. Do a 'boot -r', run 'format' then 'newfs', edit '/etc/vfstab' to automount your new disks at startup, and then run 'mountall'. But bellnexxia brings up a valid point. You might have to edit additonal files and do other stuff too (like install some software). Make sure you read the instructions for setting up your array. If it's RAIDed read the manual on setting up the RAID manager for your disk array.

Hope this helps.
