how long take in finish a servicemag for one replacement disk

[francisco82]

hi Comunity

Does anyone know how long takes to terminate the servicemag process after a failed disk replacement? or does anyone know how I can calculate the time of this process?

Not sure what you have done, but usually it stays in that status until manual interaction.

hi Torsten

 i sking it, becouse we  going to remplacement some SSD disk  for some problem with the model that we have... and we can not run the servicemag in work time... for that we need calculate how long time its proces take in order to understand in wich moment we can run that procces.

The amount of time taken to complete servicemag depends upon the "chunklet count"  and the "Drive type"

the following commands can help you determine the approximate remaining time

• servicemag status
•  servicemag status -d

The formula would be, 

• (no.of total number of unused chunklets / 3 ) /60 - NL Drives
• (no.of total number of unused  chunklets / 4 ) /60  - FC & SSD Drives

The approx relocation time for the FC chunklets is around 4 per minute and for SSD its around 8 to 10 chunklets per minute.

OK, my understanding was the replacement process has failed ...

• servicemag status
•  servicemag status -d 

the above commands can give you the real-time status of the "servicemag status."

hi  @JoshJames , thank for answer me,

 in may case y have one disk with 2889 Chunklets on used

output:

pepito cli% showpd -c -p -cg 0 -mg 22
-------- Normal Chunklets -------- ---- Spare Chunklets ----
- Used -- -------- Unused -------- - Used - ---- Unused ----
Id CagePos Type State Total OK Fail Free Uninit Unavail Fail OK Fail Free Uninit Fail
22 0:22:0 SSD normal 3575 2889 0 391 0 0 0 0 0 295 0 0
-----------------------------------------------------------------------------------------
1 total 3575 2889 0 391 0 0 0 0 0 295 0 0

NOTE: the objetive is ungrup  this phisical disk using the servicemag, remplacement for new model of the SSD disk and run again the servicemag to group it.

fallowint that you coment this is the resut:

(2889/4)/60=15

but i dont have cleare what is the result? time?, Chunklets/min? or what?

Regards... and thank a lot

Hello @francisco82 

i believe the serivemag is being run on an SSD Drive and hence the following formula would help you calculate the approximate time in "hours"

• (no. of the total number of unused  chunklets / 4 ) /60  - FC & SSD Drives

Note: take into consideration the "total number of UNSED chunklets and apply the same to the above formula to calculate the time in Hours. 

for the example

(2889/4)/60=15 hours.,

I think you have considered the "used chunklets" , instead of "unused"

please use "UNSED chunklets" and run the formula again. the result would be the time in "Hours"
