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

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.
