==RAID setup==<br />
These instructions for the RAID setup for <tt>honey</tt> come from Robyn Landers of MFCF.<br />
<br />
To reconfigure, first need to unmap the existing LUNs from the host.<br />
In the telnet session to the management port...<br />
<br />
view and edit Host luns<br />
<br />
There are two: CHL 1 ID 0 (Primary Controller) and CHL 3 ID 1<br />
(Secondary Ctlr).<br />
* choose CHL 1 ID 0<br />
** this brings up LUN 0 (logical drive 0, 279GB RAID5) and LUN 1 (logical drive 1, same)<br />
* choose LUN 0, and unmap it<br />
* choose LUN 1, and unmap it<br />
* checking CHL 3 ID 1, we find no LUNs there in the first place<br />
<br />
Now reassign the drives.<br />
<br />
view and edit Logical drives<br />
<br />
There are two: LG (logical group?) P0, a RAID5 in "good' status, and LG P1, a RAID5 in "drv failed" status.<br />
* choose P1 and delete logical drive<br />
* go back out to "view and edit Drives" and now we see those drives are in LG_DRV "none", so far so good. Back to view and edit Logical drives.<br />
* choose P0 and delete logical drive P0. All drives are now unassigned.<br />
* choose the now-blank P0 and Create Logical Drive. Yep, it doesn't know RAID6, so choose RAID5. It puts up a list of all available disks. Hit Enter to select the ones we want. Chose 0 1 2 3, then next menu gives choice of Assign spare, so chose 12. Gives summary screen: RAID5, 4 drives, 1 spare, logical drive primary. Confirm. Accept several notifications about building it.<br />
* repeat for new LG P1 using disks 5 8 9 10, with 13 as spare.<br />
<br />
Now need to combine these two RAID5 LUNs into single logical volume.<br />
<br />
view and edit logical Volumes<br />
* table is empty<br />
* select LV 0, create logical volume<br />
* select both LGs, P0 and P1<br />
* accept default write policy and logical volume assignment, create the LV<br />
* now we have LV P0 consisting of 2 LDs<br />
<br />
Next need to map this logical volume to the host.<br />
<br />
view and edit Host luns<br />
* select CHL 1 ID 0 (primary controller)<br />
* select logical Volume<br />
* select LUN 0<br />
* only choice available is LV P0 that we just created. Select it.<br />
* leave it as one big partition, not our job to chop it up at this level. Size is 418,506 MB<br />
* only choice is Map Host LUN<br />
* LV 0 partition 0 to channel 1, ID 0, LUN 0 which I assume will end up as c1t0d0 from Solaris p.o.v.<br />
<br />
All done. RAIDs are initializing in the background. Next step is at the OS level to label and partition this single logical volume.<br />
