Here is what I found out: The slots which are filled with disks at the factory are not magical = but are important. The disks are spaced in the A5200 array (Front:0,5,10 Rear:0,3,6,10) "because circuitry on the disk drives regenerate and = retime the data signals which corrects signal quality loss accumulated through = the bypass circuitry between empty slots". In English: you can't put the = disks more the 5 (4 empty) slots from one another or you may get intermittent = and strange errors. So as disks are added they should be spaced to minimize the gaps = between disks. Original Question: Gurus, This seems like a painfully easy question, but even my master reseller = can't answer it. I've looked in the FAQ, archives, and SUN's many web sites. = No luck. Are there slot restrictions for disk drives in an SUN StorEdge A5200? Should certain disk slots be filled before others? This is how the A5200 is currently setup: ---------------------------------------------------------- (/usr/sbin/luxadm version: 1.36 SunOS 5.5.1) SENA =20 DISK STATUS=20 SLOT FRONT DISKS (Node WWN) REAR DISKS (Node = WWN) 0 On (O.K.) 2000002037bea372 On (O.K.) 2000002037bedf41 1 Not Installed Not Installed 2 Not Installed On (O.K.) 2000002037ef8e7e 3 On (O.K.) 2000002037e3f7a7 Not Installed 4 Not Installed On (O.K.) 2000002037bebfbe 5 On (O.K.) 2000002037bec309 Not Installed 6 Not Installed On (O.K.) 2000002037bec333 7 Not Installed Not Installed 8 On (O.K.) 2000002037ef87a6 On (O.K.) 2000002037e3f2d8 9 Not Installed Not Installed 10 On (O.K.) 2000002037beaeea On (O.K.) 2000002037bee0f8 SUBSYSTEM STATUS FW Revision:1.09 Box ID:0 Node WWN:50800200000a1940 Enclosure = Name:a Power Supplies (0,2 in front, 1 in rear) 0 O.K.(rev.-02) 1 O.K.(rev.-02) 2 O.K.(rev.-02) Fans (0 in front, 1 in rear) 0 O.K.(rev.-04) 1 O.K.(rev.-00) ESI Interface board(IB) (A top, B bottom) A: O.K.(rev.-04) GBIC module (1 on left, 0 on right in IB) 0 O.K.(mod.-05) 1 Not Installed B: O.K.(rev.-04) GBIC module (1 on left, 0 on right in IB) 0 O.K.(mod.-05) 1 Not Installed Disk backplane (0 in front, 1 in rear) Front Backplane: O.K.(rev.-04) Temperature sensors (on front backplane) 0:36=BAC 1:36=BAC 2:36=BAC 3:36=BAC 4:36=BAC 5:37=BAC=20 6:37=BAC 7:34=BAC 8:36=BAC 9:36=BAC 10:36=BAC (All temperatures are NORMAL.)
