SMO 3.1/3.2 and AIX PowerHA issues

Hello,

IHAC who has SMO (currently 3.1P1) on a PowerHA 6.1 (AIX 6.1) server.

All backups work perfectly.

The issue comes when you want to restore (or even just mount a snapshot).

I think I narrowed the problem with Snapdrive.

First , we used SDU 4.2P1 (and it didn't detect the righ version of HUK and PoxwerHA with sdconfcheck)

I tried to upgrade to Snapdrive for Unix 5.0 and it's better since it detects PowerHA.

We do still have the issues, and I think it may be a problem of detecting a supported version of PowerHA and HostOS.

As you see below, sdconfcheck doesn't show the Host OS information: we should have a line with "Detected Host OS ....."

sl1105 /opt/NetApp/snapdrive # bin/sdconfcheck check

Detected PowerPC Architecture

Detected IBM AIX OS

Detected FCP on AIX

Detected AIX JFS File System

Detected AIX JFS2 File System

Detected AIX Native LVM

Detected AIX Native MPIO

Detected PowerHA6.1

Detected FCP AIX Host Utilities 5.1

Detected iSCSI AIX Host Utilities 5.1

Did not find any supported configurations by SDU Version 5.0

sl1105 /opt/NetApp/snapdrive # oslevel

6.1.0.0

When you do a backup mount or a restore in SMO, some snapdrive commands are run. I tried to run them outside of SMO and I get this:

/usr/sbin/snapdrive snap connect -fs /sl2105/oracle/OWPPPA/ora /opt/Ontap/smo/mnt/-sl2105-oracle-OWPPPA-ora-20120220113618248_0 -snapname n6240-2A:/vol/vol_2105_2_OWPPA_data&colon;smo_owpppa_nohacmp_owpppa_f_h_1_4028fae9359a51af01359a51b2ca0001_0 -autorename -noreserve -prefixfv SnapManager_20120220113618326

Cannot mount guarded filesystem.

The filesystem is potentially mounted on another node.

Finally, another command shows there is a problem detecting that there is a PowerHA configuration:

sl2105 /opt/NetApp/snapdrive # snapdrive config check cluster

0002-028 Admin error: Host OS is not supported for -devicetype shared operations.

Is this happening because it doesn't detect Host OS ?

Anyone has an idea of what is wrong in configuration in AIX/PowerHA/PowerVM ?

Thank you

FYI,

the reason why it was not working is the customer configured the HACMP cluster in concurrent mode.
