SVM / SDS device ID conflict situation

[cah]

We had a power outage at work this past weekend.
I was working extremely hard yesterday to bring all servers up.

One problem I encountered is that the SVM (Solaris Volume Manager, used to be Solstice DiskSuite - SDS) complained about overlaps between 2 HDs (new HDs we purchased from a vendor).

After searching on the internet for some time, I realized it was caused by the identical device ID from these HDs. SUN recognizes its own HD with unique IDs on each HD. The 3rd party HDs are NOT recognized by SUN and have the identical device ID that causes the confusion.

The solution I found is to us "rwdevid" tool.

I then checked with the vendor who sold us the HDs.
They explained and provided a document from SUN.
Basically, the document describes how to make it work (just like how "rwdevid" does it, the vendor said).

First, find HD's vendor and product.

Code: Select all

Second, add the following lines in /kernel/drv/sd.conf (make sure to use the right vendor and product number):

Code: Select all

sd-config-list=
     "SEAGATE ST3146855LC     ", "workaround";
workaround=1,0x8,0,0,0,0,0;

Make sure the Vendor occupies the first 8 characters of the total 24 characters in the first pair of "".

Third, reboot (no need for reconfigure).

That should be it.
The disks can be put into mirror again.
