To avoid downtime during Check disk activity in SAP servers

Former Member

Hi Everyone,

Due to errors in logical drives , often this CHKDSK activity has been carried out in SAP servers which require a downtime for carrying out this task. Could any one suggest if we can run this activity without any downtime or any alternatives/proactive measures can be done ? Please help on this.

Thank you all

Regards,

Kavitha.

I would in the first place check why those errors are occuring. If filesystems get corrupted there is a reason for that. Running chkdsk is not a normal activity.

Did you try to dig into the problem?

Thank for the reply Markus.

I am trying to know about the errors which causes the failure but, as it cannot be tracked from our end , we are waiting for inputs from right team. Mean while , Can't we get any solution/alternative for it regardless the error ?

If your filesystem gets corrupted, you can always be happy, if chkdsk is able to repair the damages!

I would keep the system stopped when this happens again and/or switch hardware until you know, where the problem is. If at some point the filesystem damages are too big and you're unable to repair them, you will have data loss.

But the problem is, this activity has been carried out as a proactive measure for some errors occuring in logical drives to avoid crashes/big problem. In recent times , this activity has been done many times and some critical servers cannot be made offline for long time. Is there any way we can avoid this dowmtime for these type of servers when they carry out CHKDSK?

The root cause of this need to be found....

This is the same as trying to change tires on a car while it is driving on a highway, it's just not possible. How should an operating system repair a filesystem while the system is running and trying to read and write just from that filesystem?

No DB2 for z/OS issue, moved thread to Windows forum.
