hi,
with vsphere 5.5 ànd using RAW disks my concern is to follow up the smart status
there are some documents that redirect you to the syslog page where i could find smart details like :
2015-01-22T20:02:08Z smartd: [warn] naa.*********b: above TEMPERATURE threshold (176 > 0)
2015-01-22T21:02:09Z smartd: [warn] naa.*********b: above TEMPERATURE threshold (171 > 0)
2015-01-23T06:32:41Z smartd: [warn] naa.*********b: above TEMPERATURE threshold (253 > 0)
2015-01-23T09:32:42Z smartd: [warn] naa.*********b: above TEMPERATURE threshold (181 > 0)
i do not know if there are any better tools to report on current disk status..
first of all those values here are fahrenheit i believe but 253 i impossible .....
even it was a glitch value like 170 (=76°C) would be impossible
second i prefer to have to be alerted when certain values exceed a certain threshold.
would this require me to run some vcenter or something like that or are there alternatives ?
some further checking:
getting SMART from a regular disk on a server SATA port (my sata controller is defined by Vsphere as "Wellsburg raid controller") runs fine
but the value is still questionable.
i do wish to know if additional tools or plugins would be usefull.

Parameter Value Threshold Worst
---------------------------- ----- --------- -----
Health Status OK N/A N/A
Media Wearout Indicator N/A N/A N/A
Write Error Count N/A N/A N/A
Read Error Count 100 16 100
Power-on Hours 99 0 99
Power Cycle Count 100 0 100
Reallocated Sector Count 100 5 100
Raw Read Error Rate 100 16 100
Drive Temperature 214 0 214 <------i assume this is 214°F = 101°C which is impossible...
... or i may have to substract 100 from the value so : 214-100=114°F =45°C which is more acceptable
a device on my sas 2308 controller does not pass smart info
if something goes wrong i must assume my sas controller will warn me 'somehow' ...
# esxcli storage core device smart get -d naa.xxxxxxxxxx
Error getting Smart Parameters: CANNOT open device
if this question would fit better into another section by all means feel free to move it
any additional information how small is appreciated.
I noticed the same thing, My ssd are reporting 37 & 44 but my regular HDD are saying 139,140. The 37 & 44 for ssd seems reasonable as Celcius as the ambient temperature should be around 45. But 140 C seems high.
