Re: sar -d

HI torsten.

Is it avvisable for superdom to have OS on the sigle spidle disk . Or there is huge deference if it is on a FC array.

However, please post a complete

Hope this helps!

Re: sar -d

Hi

a) you have a disk bottle neck when avwait > avserv. Only one metric meets this condition: c31t15d3.


The DS2100 series of SCSI bays are standard to superdome O/S disks. They are not internal per se, and they will be about 15 feet away SCSI cable connected. Here is where you will find you O/S drives.

Note: Since you can see the disks, there is nothing wrong with the DS2100. Also note that besides a back plane, slots and drawers for your disks to slide into, there is nothing that shows up in ioscan.

Again, if you can see the disks in the DS2100, then the DS2100 is working fine.
