Solaris

Due to speed mismatch, the server kept crashing. Sun suggests that I need to move the two HBA cards from the 66Mhz to the 33Mhz slots. There are tons of disks that are connected to these HBAs and I have Veritas volume manager.

Does anyone have a list of what I need to do prior/after moving to the new PCI slots? One thing I know is the controller names will be different, eg. the old c6 would become like c3, etc.

Simplest way would be, assuming that you are not using a system with removable IBs or CPCI.

Code:

init 5

move the cards

Code:

{ok} boot -r

It should be as simple as that.

If using vxvm then you don't need to update vfstab, because the dgs are tracked using the private regions, so that makes your situation much easier.

If it doesn't mount everythig up properly, then just do

Code:

vxdctl init
vxdctl enable
vxdg import mydg # for each disk group
mount -a

I have not heard of server crashing due to PCI slot speed mismatch.
The higher speed PCI should step down to a lower speed automatically upon detecting a lower speed device.

It can happen, and a multi speed HBA will not force the BUS to 33Mhz, so you can a system with two of the same model HBAs running at two different speeds.
