Hi Trunks,
Did you manage to get your problem sorted?
I am busy implementing an RMAN backup on a non-global zone and it is failing with the same error as you have getting (error 6 on Netbackup)
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on ch00 channel at 08/27/2008 15:48:08
ORA-19506: failed to create sequential file, name="0hknog3t_1_1", parms=""
ORA-27028: skgfqcre: sbtbackup returned error
ORA-19511: Error received from media manager layer, error text:
VxBSAValidateFeatureId: Failed with error:
Serevr Status : Cannot connect on socket
NB: I have used the similar script on a another client which was not a zone and it worked 100%.
Please assist.
