I bought "As-Is" a 3par rack containing a 4-Node 7450c ( E7X62A ), having 4x E7X87-63001 Controller modules, 8 x HP M6710 ( QR490A ), and a DL320e SP. No disks were supplied. I am new to 3par. My understanding has been gathered entirely over the past week, trying to get this kit operational.
I've never seen this kit operating, so I may have purchased 3 dead nodes, and 1 maybe ok / maybe not node. I have cabled up just the 4 Nodes. Power, network, io, and powered the lot on. And what I describe here, is how this I received this kit.
Node 3, power on, almost immediately flashes some green. Leds for network, fibre (onboard + 4x 8gb expansion), all flash some green and look healthy. IO connector leds appear healthy, although saying no link. With a console cable connected, I get output and can logon.
Nodes 0,1,2, Power on, never do leds flash, except for Hotplug and Fault, which flash together at the same time. The controller will power on, flash those two leds a few times, then go dark for a few seconds, then come back on blinking forever. With a console cable connected, I get zip. Messing about with the console, unplugging, plugging back in, etc. sometimes I get a scrambled character. One time, I got a quarter page of scrambled characters. Progress I thought, more is better than less right?
Internally on these nodes, there is 5x led for POR STATE (Power-On-Reset), which show leds 0,1 green. Node 3, these same leds show 0,1,3,4 green.
I have noticed that on the enclosure for Nodes 0 and 1, both battery leds show failed. Enclosure for Nodes 2 and 3, appear ok, however, initially, the battery led indicated warning / sw fixable fault, but that seems to have cleared.
I have swapped the ssd-boot disk between nodes. Node 3 boots ok using ssd-boot from other nodes, but not vice-versa. I have connected Node 3's ssd-boot disk to my linux workstation via SATA cable, and noticed the log partition was 100%. Errors were throughout recent history regarding unavailable space to write logs, so I deleted a 36Gb system log archive.
I have tried swapping all parts from Node 3 with another Node. Node 3 always boots ok, other nodes do not. Always same issue. blinking hotplug and fault.
I have tried removing / swapping the button battery. Currently I have one node with button battery removed, I am hoping that eventually whatever it was keeping charged will reset, and maybe clear whatever is stopping it from posting.
My next step I suppose is to examine the logs on the other nodes.
