we have 2 firewalls, which grouped together as active/active failover pattern with 2 contexts: admin and Ctx1: we are able to launch asdm either by ASDM launcher or web based for FW1, which is active for admin, but when we tried launching fw2 which is active for Ctx1, we received a error message:the device does not have the appropriate Device Manager image installed. ASDM Launcher supports ASDM 5.0 or higher."
But when I console into every firewall: I saw the ASDM version is 521 for every FW:

19 -rw- 20012 01:00:36 Jun 05 2008 ctx.cfg
I donot think it is ASDM version issue, i think it is because of context issue, when I changed to different context I got different result:
SINFWL001/admin# sh asdm ?
history Show contents of Device Manager history buffer
log_sessions Show current Device Manager logging sessions

SINFWL001/admin# sh asdm his
