Replacing 2gb mcdata switches with 4gb/sec brocade switch
Folks,
We have 7 Mcdata M4500 switches in our backup fabric and we want to replace it with one Brocade 48k switch. Our concern is that the device files will change when we replace the switches. Please answer the following questions:
1) Is there a way to preserve the device files?. What if we ISL the brocade switch into the mcdata fabric and then one by one remove the mcdata switches. Will this preserve the device files?
2) Is it possible to copy the zoning from the mcdata switches to the brocade switch without connecting the new switch to the fabric, if so how to do it?
3) If i connect the brocade switch to the mcdata fabric temporarily and then remove it, will all the zoning information be automatically copied to the brocade switch?
Thanks in advance for all your help.

i am in TSM shop myself
. I would not worry about tape/changer devices change their path. It's very easy to modify device path in TSM. Once you connect your devices to new switches, yes ..they will get new fcid from the switch and it will reflect in native device name. Especially on HPUX as its' device path contains domain id.
If it were me, i would simply cutover to the new switches without monkeying around with merging fabrics, changing fabric modes ..etc. Are you using Connectrix Manager to manage your McData switches ?

i remember looking it up for somebody else on this forum, what i found was that in order to connect McData to Brocade, one of the switches had to change its interop mode which results in it wiping its existing config. I don't think you want to do that for neither of your switches. I would export zones/alias information from Connetrix manager (xml files) and script a zone/alias creation for Brocade switches. This way you have an easy way to roll back if systems do not work on Brocade fabric.

Thank you dynamox. We are using connectrix manager to manage the mcdata switches. For some reason we are trying to avoid to modify the device path. Please could you answer my 3 questions?
