Sun Storage A5200 picking random hot spare

Hey Guys,

I have a Sun 280R that runs Solaris 9 and Veritas 3.5.

Attached to this machine are 2 x A5200 storage arrays (fibre).

I have them setup so they are on a RAID 5 and a couple of hot spares. B is a mirror of A.

If a disk on B goes down in the array, for some reason a dosk from array A will become the hotspare. As you can see, this really isn't the best way of having a system like this.

Could anyone tell me how I can get this working so if a disk out of array B goes down, it will pick a disk from B to rebuild or add itself to the RAID.

Kind regards and TIA

If "arrays: are disk boxes connected to same controller then there is no way around - they use RR to select hot spare and you cannot do anything about it.

Gheist,

Thank you for your reply. This machines has 2 controllers. One running one array and the other running another array.

TIA

Is this soft array by veritas?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

hot-relocation attempts to use the disk that is closest to the failed disk. The value of closeness depends on the controller, target, and disk number of the failed disk. A disk on the same controller as the failed disk is closer than a disk on a different controller. A disk under the same target as the failed disk is closer than one on a different target.

You can designate one or more disks as hot-relocation spares within each disk group.  so if your volume are create under different disk groups, I guess you can assign disks of particular controller as spare disk.

Just a suggestion, I'm not sure how your volumes are setup in your environment.

It is impossible to set specific disks as hot-spare for particular array in same disk group.
Disk failure is extreme situation. I assume you can move array back into disk shelf after changing failed disk.
