Comment on Database Replay by example by Yannick Jaquier Mon, 16 Jul 2018 09:16:29 +0000 Abhijit,

Thanks for comment.
Database Replay “only” automate what you can 100% do manually. I mean go to your application owner and ask him to test his application on a test upgraded database. He should be able to tell you if working or not.
You might also want to consider SQL Plan Management

Comment on Database Replay by example by Abhijit Jadhav Fri, 13 Jul 2018 14:37:46 +0000 Yannick, enjoyed your post.

Comment on Veritas Volume Manager (VxVM) command line examples by Yannick Jaquier Mon, 09 Jul 2018 10:22:32 +0000 Hi Fred,

Comment on Veritas Volume Manager (VxVM) command line examples by Fred Fri, 06 Jul 2018 12:27:41 +0000 Hi Yannick,

Occassionally, found this a bit old article.
I have HP MSA 2050 storage and connected my servers to them via iSCSI ports. OS is RHEL 7.2.

I have VCS installed and the problem is that VCS services loaded before ISCSI finished scanning paths. So VxDMP not aware about LUNs.

I can refresh it manually with “vxdctl enable” or “vxdisk scandisks”. But I would like to have more standard solution.

May be you have some tricks for that.

Thank you in advance.
