ArchiveLogs on NetApps ?


We've just begun our first NetApps [9iRAC on Linux] implementation.

What I've found in testing so far is

  a)  Writing ArchiveLogs to a NetApps Filer volume seems to be very slow 
[5min for a 100MB
logfile against 30seconds on local disks]  Do the ArchiveLog Dest volumes 
have to be mounted
with the same NFS options as the Database Files volumes ?

b) Testing recoveries using SNAP CREATE and SNAP RESTORE we find that we 
frequently
encounter a corrupt block in the last ArchiveLog being written to the 
ArchiveLog Dest volume.
Any ideas why ?

Backup :
     BEGIN BACKUP
      Snap Create Database Files Volume
    END BACKUP ;;  ARCHIVE LOG CURRENT a few times
      Snap Create ArchiveLog Files Volume

Recovery :
      Snap Restore Database Files Volume
      Snap Restore ArchiveLog Files Volume
     RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL
