"Rean/Write error in named pipes" during Exchange Restore

[shaker99]

We're trying to restore a large Exchange 5.5 IS Database and keep getting this error. We've tried to restore from 5 different backups and to two different servers, it just won't completely restore. We have Arcserve installed on the Exchange server and are doing a restore from a tape drive connected directly to it, nothing is going through the network.

Any help would be appreciated!

What is the exact error?
Are you SP3 on ArcServe?
SP4 on Exchange?
Is the server you are restoring the same as the on backed up?

Thanks for you reply logixman!

The actual error is: "E8603 Failed to write to database. (DBNAME=Information Store\F:\exchsrvr\MDBDATA\PRIV.EDB, EC=Backup Agent Error -- (69) "Read/Write error in named pipes.".)"

We're at SP2a on ArcserveIT 6.61 (as instructed by CA support, is there an SP3?)

SP4 on Exchange 5.5 and we are NOT restoring to the same server. The server we are restoring it to has the same name, org, site, patches and access to the same SAM. I don't think it's the Exchange or server config though since we've tried various configs and different hardware (I mean everything from diff servers to diff SCSI cables).

Spoke to CA support today and they had me do a registry change to force the agent to use TCP instead of Named Pipes. That didn't help since I got the same error on the next restore attempt.

Hope to hear from someone!

Are you recreating the mailbox and everything before attempting the restore? Also make sure the agent is correctly set up and everything.

hope this helps

Thanks for the reply, I'm actually just restoring the entire IS so a mailbox doesn't have to be configured. I believe you only need to configure the Exchange agent and setup a mailbox if you intend on doing brick level backups and restores.

I've setup a new exchange server and created some test mailboxes to see if I could back it up and restore it. Everything worked fine without creating a mailbox or configuring the agent so I think that parts OK.

Cheers

No, even for Information Store restores you need the agent. It does not need a mailbox, but its needs to be configured for TCP and use the EXSERVICE account...because restoring a live priv.edb requries the Backup RPC service to be running on the target.

Yeah, I have the Exchange agent installed, I meant you don't have to configure the mailbox option on it. The restore begins with no problems, it's only after about 60 to 90gb that it fails with the Read/Write error.

do you have your antivirus disabled.... this may be causing errors with named pipes, and and set it back to using named pipes.

I don't have anti virus running on my target server at all. One thing that is interesting is that I have Mcafee Group Shield 4.5 running on my production server. Arcserve says it's not compatible with their Exchange agent but it backs up fine. Who knows!?
