HP EVA P6000 LUNs not present

We have 3 LUNs created and presented to 1 linux server. But after a few times of restarting the Linux server, we still cannot found it using fdisk -l

The 3 LUNs are under a replication group from PROD to DR. The 3 LUNs are in DR.

As part of troubleshooting, we created a new LUN and present to the same Linux, once Linux is restarted, we can found it.

Any ideas? Thanks.

Hi

Luns in DR are write protected and it's not good to use them

but you can create a snapshot and present it to your server

Re: HP EVA P6000 LUNs not present

Actually, we have

1. Failover and suspend in DR replicate group
2. Present the 3 LUNs to Linux
3. Reboot Linux
4. Create a new LUN in DR
5. Reboot Linux
6. The newly created one can be found

To use the DR LUNs, do we need to create a snapcopy of all the LUNs? And after we mount them, perform the testing, can we delete it?

Thanks.

Re: HP EVA P6000 LUNs not present

hi

you are not clear what your problem is.

as I said destination LUNs in DR are write protected so if you want to test them

the best way is to create a snapshot of the LUN present to your server and work on the snapshot.

when you finish your test you can delete the snapshot.
