CurupiraConfiguration

Hardware notes

Curupira is an SGI 3200 server. It has C-, G-, I-, and D-Bricks. This twiki concerns the D-Bricki hard drive configuration.

Viewing the D-Brick

The D-Brick consists of 12 drive bays of which 10 are populated. They are numbered differently depending on what SGI data manual or section is referred. This is a view of the drive looking from the front of the machine, numbered col/row, #drive, and system number (dks0dXXXvh):

1/1   #9      2/1  #10      3/1  #11      4/1  #12
dks0d122vh       X             X          dks0d125vh

1/2   #5      2/2   #6      3/2   #7      4/2   #8
dks0d118vh    dks0d119vh    dks0d120vh    dks0d121vh

1/3   #2      2/3   #3      3/3   #4      4/3   #1
dks0d115vh    dks0d116vh    dks0d117vh    dks0d114vh 

Drive grouping

The two drives at the bottom corners dks0d115vh and dks0d114vh are reserved for the system.
The drives dks0d116vh, dks0d117vh, dks0d118vh, and dks0d119vh are striped and mirrored by the drives dks0d120vh, dks0d121vh, dks0d122vh, and dks0d125vh.
The two drive groups are managed by the XFS volume manager referred to as XLV:
