SYMPTOM

Customer complains of duplicte recovery images being seen in vmPRO when attempting to restore a VM, see image below...

 

 

 

CAUSE

The cause here is due to the customer having both source anf target DXi's configured as storage for the vmPRO appliances. Moreso both DXi's contain the same share name as each other

 

Both the smr_3 and smr_8 databases contain entries for SVI007:
[gfaith@localhost var]$ grep SVI007 smr_*
smr_3.output:3 \N SVI007 564d6dcc-921a-a922-3438-589e4bc57cdf 1370847595 2013-06/2013-06-10-1559/kiki/SVI007 \N 10.24.1.190 VMI001.asahikogyosha.com Resources \N 1

smr 3 and 8 correspond to the following storage devices, which have different ip addresses but same share/subdir:
COPY backup_target_smr (entry_id, gen_id, host, share, base_path) FROM stdin;
1 \N 10.3.2.104 /Q/shares/vmpro-sub
2 \N 10.3.2.104 /Q/shares/vmpro-main
3 \N 10.24.3.1 /Q/shares/vmpro-kiki
4 \N 10.2.2.104 /Q/shares/vmpro-main
5 \N 10.3.2.104 /Q/shares/vmpro-sub SubCenter
6 \N 10.24.3.1 /Q/shares/vmpro-kiki ki,ki
7 \N 10.2.2.104 /Q/shares/vmpro-main MainCenter
8 \N 10.3.2.104 /Q/shares/vmpro-kiki
9 \N 10.3.2.104 /Q/shares/vmpro-sub SUB-AD
10 \N 10.2.2.104 /Q/shares/vmpro-main MAIN-AD
11 \N 10.2.2.104 /Q/shares/vmpro-main SV0019

 

 

RESOLUTION

There are a couple of ways in which to resolve this condition...

 

1)    remove the target DXi from being used as storage for the vmPRO appliances. As soon as the target storage is deleted the duplicate recovery images disappear.

2)    change the share name on the target so they are different to the source, then resync the replicated partition between source and target DXi's.

 

 

ADDITIONAL NOTES

The duplicate recovery images could be due to either of the following conditions...

 

 

a)    Different network interfaces on the same DXi connecting to different networks. 

b)      Different DXis but one is the replication target of the other.
