I have done this a few times before and documented my steps before, but this time, I am out of luck.
Any ideas on the following? For some reason the new physical disk was assigned to a new "unit 1". The other three are on "unit 0". So I deleted that unit: tw_cli maint deleteunit c0 u1 Then did the rescan: tw_cli maint rescan That worked but it was flagged as (NO UNIT). So I created it: # tw_cli maint createunit c0 rspare p1 Created unit /c0/u1 (Unit Drive Utilization = 100% And that put it back at u1. I don't see any docs on how to get it to go to u0 (unit 0) -- it is not an option in the docs and I tried it and it failed. So rebuilding anyways: # tw_cli maint rebuild c0 u1 p1 (0x0B:0x0031): Rebuild unit ok And now the spare exists but it is not part of the u0 RAID5 which is still DEGRADED. So this is what the system has: # of units: 2 Unit 0: RAID 5 894.27 GB ( 1875421056 blocks): DEGRADED Unit 1: SPARE 298.09 GB ( 625142448 blocks): OK # of ports: 4 Port 0: WDC WD3200SD-01KNB0 WD-WMAMR1568561 298.09 GB (625142448 blocks): OK(unit 0) Port 1: WDC WD3200AAJS-00RYA0 WD-WMAPZ0120885 298.09 GB (625142448 blocks): OK(unit 1) Port 2: WDC WD3200SD-01KNB0 WD-WCAMR2111267 298.09 GB (625142448 blocks): OK(unit 0) Port 3: WDC WD3200SD-01KNB0 WD-WMAMR1461915 298.09 GB (625142448 blocks): OK(unit 0 (The WD3200AAJS-00RYA0 is the new disk that just replaced a bad WD3200SD-01KNB0 originally at Port 1 and unit 0. Here is my DEGRADED RAID5: ... Unit /c0/u0 --------------------- Status: DEGRADED Unit Type: RAID 5 Stripe Size: 64k Size: 894.27 GB (1875421056 blocks) # of subunits: 4 Subunit 0: CBOD: OK Physical Port: 0 Logical Port: 0 Subunit 1: CBOD: DEGRADED Physical Port: N/A Logical Port: 1 ... I can't see in the 3ware docs how to make that p1 on u1 be on Unit 0. I want to replace that DEGRADED Subunit 1 (Physical Port: N/A) with that new disk. Any help or pointers would be appreciated.
