Mirroring the System Drive

Jorge Cocomess — Wed, 15 Aug 2007 18:29:19 GMT

Greetings,

I just realized that my system drive (sysdisk) is a JBAUD device. Is there a way to mirror this drive after the fact or I have to recreate the mirror from the getgo? My openVMS version is currently at 7.3-2 - I have multiple controllers setup to talk to this server, which they are HSG70 & HSG80.

Please provide your advice.

Thank you in advance.

Jorge
