PS5000e member offline - status light indicator light?
We have an issue with our PS5000e SAN. It's not a mission-critical device and we are in the process of moving off of it, but we need to get it back online if possible.
This morning the member went completely offline. I can connect via web UI, but it just says member offline. Connecting to CLI indicates the same. All commands in CLI are executing extremely slowly, and occasionally I get warnings like: "Logger daemon is losing messages because offline disks are generating more events than the daemon can handle."
Unit is in a datacenter 500 miles away, so I had remote hands send me pictures of it. One drive shows amber, remaining 15 drives all have green lights, so the failed drive shouldn't have caused it to go down.
show recentevents returns nothing.
On the back of the unit, everything looks fine except for one amber next to a label with a wavy line (possible power issue?). Picture below:
Before I get too much further with taking action I'd like to know what this light means if possible.
Thanks for any help!

Thank you Don for the reply. I've generated diag files that I can send to Dell if they'll open a ticket for me since this is obviously beyond support.
Based on what I've read, I tend to agree with you, it's my understanding that if a member goes offline due to a drive failure, it's toast.
And then confirmation...
raidtool confirms RAID has faulted beyond recovery
thanks for the raidtool suggestion - I actually had to run:
GrpName> su exec 'raidtool' (for the benefit of future readers of this post)

Excellent information Don, THANK YOU! I had considered doing a restart earlier but was of the same mindset as you - preserving anything we can in memory. Plus who knows what kind of havoc shutting the thing down might wreak.
The data isn't nearly as important as the time and level of effort to reconfigure.
Going to give Dell a call now, you've been super helpful and I really appreciate your time.

Don,
I worked with Dell for a while and we were close but no cigar. Actually got it to come back online briefly but it soon shutdown again. The drives are just not healthy enough. Looked into data recovery and I talked to the fine folks at DriveSavers. Sounds like they have a good service there but very expensive...but it would be well worth it to recover some seriously important data. Probably not going to fly in our case b/c it's just going to save us some time and effort...no real data loss.
I will say this though, I was absolutely shocked at how helpful Dell support was with this. I didn't think they would even speak with me given the age of the unit and obviously no support, but at no point was there a single hesitation in giving me help. We even did two calls as the SAN is 500 miles from here and I had to coordinate remote hands. Just outstanding service. Try getting that level of support from Cisco without a contract, ha!
Thanks again,
Eric

Hello All,
I am new to Dell Equallogic SAN. some how i am managing PS6500 SAN box remotely from group IP. We have two members member1 having 20 TB and member2 having 104 TB capacity.
From past two month we are seeing issues in member1 as disk are failing one by one. we noticed and moved all data to member2 last week. Yesterday Member1 was down. current status showing offline state and raid is fault as per event logs..
So if we decommissioned member1 alone is its effect to any thing in member 2 ? some one can explain this please...
Storage Array firmware on both members - V5.2.4 (R255063)(H1)
Thanks,
Teja

Unfortunately no Don. support ends long back as 09-07-2014 member1 and meber2 05-31-2015.
I am looking for fimrware to download and test in member1 then proceed for member2. can you help on that where i can download 5.2.x->6.0.11 ?

i am apologies for this as i was mentioned in ongoing conversation, As i thought its related to some what my issue..
yes both are different pools. only one empty volume is offline which is coming from member1. so as per your update i will delete the member1 and upgrade the firmware for rest of member.
Regards,
Teja
