EVA4000 Re Initialization

Redhat_HP — Fri, 29 Nov 2013 02:17:22 GMT

Hi,

I have a EVA4000 and it is mounted to few servers. The storage array controlled by a separate server installed command view EVA.

Last week i have noticed that one of the HDD of the array had flailed and to replace failed HDD I tried to login to command view EVA but the storage system was not listed there and then I found out that it was not functioning due to failure of the server fiber HBA.

I have replaced the failed HBA with a new one and tried reopening command view EVA but the storage system was not discovered so when i click on discover the EVA array shows as an uninitiated array.

Since the current storage drives mounted to few production servers I am worried about re initializing the storage system since I don't know whether it would destroy all data.

Please let me know if I initialize the storage whether it would destroy all data and configuration.

Regards

Jeffry

Yes, you clear and delete everything.

Don't do this!

How about a screenshot?

Hi Torsten,

I don't have access to the system now. I will post the screenshot as soon as I get access to the system.

I am worried about how to replace the failed drive without having access to my command view EVA.

You need command view to check the status of the drive and group the disk once replaced. But don't worry, meanwhile the array have usually done a rebuild and should be fully redundant again (even with the bad disk still inserted).

Hi Torsten,

Thanks for the quick reply.

Any advice on replacing the failed drive with a new drive without access to command view EVA?

In case If second drive also failed would it affect production systems?

Do you know why the current storage not recognized by command view EVA after replacing the failed FC HBA

If a drive failes, the array will rebuild and is fully redundant again. If the next disk fails, the array will rebuild and is fully redundant again ... until there is no more space.

After changing the HBA - did you check the zoning of the switch?

Hi Torsten,

I have not checked the zoning information of the switch I just plugged the same cable removed from the failed HBA and have not done any modifications on the switch also have not configured any zoning on the switch but still the new HBA sees the storage as uninitialized.

Do you see the array as uninitialized or unmanaged?

You should still be able to explore the hardware and see the status summery. Can you do this?

Hi Torsten,

I ll get back to you on this by tomorrow as earliest as possible with screenshots once i get access to the system.

Does your server has 1 or 2 pathes to the array?

CV speaks to the master controller only, so make sure the server can "see" the current master controller of the array (better both controllers).

What XCS version is running, what CV version you are using?

Hi Torsten,

I have re seated the fiber HBA and cables and started the server and then It showed the EVA array.

Now next step is to replace the failed disk and adding it to the array.

Thanks for the support you given to me on this.

Thanks and Best Regards
Jeffry
