Good day for all!

Few days ago its appear some weird (for me) record in 3Par system when client started checkhealth comand:
3pf400-02 cli% checkhealth -svc -detail
Checking alert
Checking cabling
Checking cage
Checking date
Checking file
Checking ld
Checking license
Checking network
Checking node
Could not check node: unable to convert date-time string "2016-11-29 18:17:41 YEKT"
Checking pd
Checking pdch
Checking port
Checking rc
Checking snmp
Checking task
Checking vlun
Checking vv
Checking sp
Component ----------Description----------- Qty
License Licenses which have expired 1
pdch Chunklets on remote disks 1
vlun Hosts not connected to a port 57
vlun Paths not reported by host agent 108
....
....
Honestly i don't have any skills in 3par systems.
Garanty contract for this storage unit already has expired and it is because i can't ask HPE.
If you know what does it means this record (about unable to convert date-time string) please give some reply for me.

Thanks

Hi,

It says the correct date time:

cli% showdate
Node Date
0 2019-07-26 15:21:16 CEST (Europe/Budapest)
1 2019-07-26 15:21:16 CEST (Europe/Budapest)

I think this is the same error I had about a month ago and just like you a showdate was fine. In my case the hardware clock on one node was in a messed up state and I was told the solution was to reboot the node. I asked if this was a major issue or if I can run like this for a while without issue and was told I can run like that without issue. I think I was applying patches with HPE which is when I saw the checkhealth error; we still applied the patches without issue and I opened a new case for this problem.

This is what HPE support told me about the error after their initial analysis:

Code:
This error indicates that the HW clock on the nodes is not the same and we did logged into array and found that Node 3 has issues.


root@... Thu Jun 27 12:16:09:~# onallnodes "/sbin/hwclock"
Node 0:
Thu Jun 27 12:17:14 2019 -0.515942 seconds

Node 1:
Thu Jun 27 12:17:15 2019 -0.968927 seconds

Node 2:
Thu Jun 27 12:17:15 2019 -0.047120 seconds

Node 3:
hwclock: select() to /dev/rtc to wait for clock tick timed out: Success




I rebooted the node but checkhealth still reported an error:

Code:
Node 3 time and hwclock are not same


Support logged in again and ran the same command and said everything was fine (node 3 returned a date this time) but I noticed the time and date were way off which is what triggered the warning about time and hwclock not being the same. After they adjusted the date/time (when logged in as root I assume) the error went away and I've been ok since.
