SMSAP with SnapVault and Protection Manager

We have an SAP server who's running SnapManager for Oracle with the following volumes and qtrees mounted via NFS:

 

linuxsap:~ # snapdrive storage show -all

NFS device: netapp2:/vol/DEV_ORA_SAP/DEV_ORACLE mount point: /oracle (non-persistent)

 

NFS device: netapp2:/vol/DEV_SAPDATA mount point: /sapdata (non-persistent)

 

NFS device: netapp2:/vol/DEV_ORA_SAP/DEV_ORIGLOGA mount point: /origlogA (non-persistent)

 

NFS device: netapp2:/vol/DEV_ORA_SAP/DEV_ORIGLOGB mount point: /origlogB (non-persistent)

 

NFS device: netapp2:/vol/DEV_ORA_SAP/DEV_USRSAP mount point: /sap (non-persistent)

 

NFS device: netapp2:/vol/DEV_MIRRLOG/DEV_MIRRLOGA mount point: /mirrlogA (non-persistent)

 

NFS device: netapp2:/vol/DEV_MIRRLOG/DEV_MIRRLOGB mount point: /mirrlogB (non-persistent)

 

NFS device: netapp2:/vol/DEV_ARCHLOG mount point: /oraarch (non-persistent)

 

SnapManager for SAP is configured for using Protection Manager to do a SnapVault update after the backup (snapshot) of SnapManager for SAP:

 

SnapVault relations:

 

netapp2> snapvault status

Snapvault is ON.

The problem is that Protection Manager is only updating 1 of the qtrees of a volume. Like you can see in the DEV_ORA_SAP volume, only 1 relation is updated.

We have already created the relationship manually and automatically with Protection Manager but the result is still the same.

 

We cannot use a Volume relationship as we use SnapManager for SAP to create the backups. SMSAP is configured to protect the backups. As we create only 3 volume relations, SMSAP will not run as he is not finding the relationships for the qtrees.

 

What do we need to do to have a successful SnapVault update after a backup with SMSAP.

    Hi Tom,

     

    the reason for the issue that you're seeing is the following: SMSAP (as well as SMO) only takes care about relevant data/qtrees for a consistent Oracle backup. This includes:

    - the oracle data files --> in your case

    netapp2:/vol/DEV_SAPDATA/- netapp1:/vol/VAULT_DEV/smsap_linuxsap_dev_netapp2_DEV_SAPDATA Source         28:49:17 Idle

    - the archive log files --> in your case

    netapp2:/vol/DEV_ARCHLOG/- netapp1:/vol/VAULT_DEV_ARCHLOG/SV_DEV_ARCHLOG Source         28:48:56 Idle

    - the oracle control files --> in your case most probably

    netapp2:/vol/DEV_ORA_SAP/DEV_ORIGLOGA netapp1:/vol/VAULT_DEV/DEV_ORIGLOGA Source         28:49:17 Idle

    netapp2:/vol/DEV_MIRRLOG/DEV_MIRRLOGB netapp1:/vol/VAULT_DEV/DEV_MIRRLOGB Source         28:49:17 Idle

     

    (see SMSAP manual "Full online backups" ff. for details)

     

    Only those qtrees will be considered in PM for snapvault updates. If you want to protect the complete SAP filesystem you could either:

    1. Put the remaining Qtrees in a separate dataset and assign an appropriate policy (with local backup schedule) --> which leads to additional snapshots

    2. Put all filesystems in the same qtree as the one relevant for SMSAP (e.g. only one qtree per volume in your case)

     

    Hope that helps,

    Tobi
