EVA 4400 upgrade

[Magnus Appelgren]

Hello!

I'm about to upgrade our SAN enviroment. I have the follwing EVA, switches etc:
2 EVA 4400 running CA with fw 09501000
3 HP SAN switch 4/16 with fw v6.1.0h
1 HP SAN switch 8/24 with fw v6.1.0h
2 SAN appliance servers with CV-EVA 9.01

This is diveded on two locations with LAN and long range fiber access.

Mainly we have a vmware enviroment but some physical proliant with windows server 2003

We have two c7000 with BL480 blades.

I have already upgraded both WOCP and am about to continue upgrade with CV-EVA, then secondary EVA and if everything works well production EVA and the switches. Server drivers/firmware will be upgraded also.

Do the forum have any suggestions?

Regards

Magnus

Hello,

More information is needed.

Are you running CA between the arrays ?

Please note that if you upgrade to XCS 09522000 it is an OFFLINE upgrade which requires full power cycle.

Yes the two EVA's are running CA between arrays.

Hello,

If you read the Updating Product Software link: http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c01846362/c01846362.pdf

Page 37 regarding suspend operations when doing upgrades in a CA setup.

Thanks.

How do I easiest disable isl links?

How does log size work, it says 102.4mb but I guess its gonna log until disk space runs out? When disabling CA that is.

Is the switch upgrade straight to 6.2.1 or do I have to upgrade to some firmaware before. Cant find any good guide for upgrade.

Hello Magnus,

For disabling ISL links you can just disable ports in the switches - i prefer disabling the CA zone instead.

When you suspend the CA group it will log to disk, and merge when you resume the replication. - It will log until i reaches the specified log disk limit, or the diskgroup runs full.

You can upgrade directly to 6.2.1 from 6.1.0h

Ok so I will have to increase log size or monitor it during upgrade so I dont accidently will have to do full copy which would be a disaster.
