Hi, We have a Inserv F400 with 4 failed NL Disks which need replacing with new ones. Does anyone have the step-by-step instructions on how this is done? From my understanding this is not as straightforward like an EVA where disks are simply removed and added.
Could you help!
P.S. This thread has been moved from Storage > Training & Education to Storage Area Networks (SAN) (Enterprise).

What version of the HP 3PAR OS do you have?
>Does anyone have the step-by-step instructions on how this is done?
Have you looked at the CLI Admin manual?
The command is "servicemag start" on each magazine. After replacing, you do "servicemag resume".

SolutionHi,
OS Version is 3.1.2. I though you would have to run 'admithw' to submit new hardware?
Do you know the start to end proceadure i.e.
remove broken disks (run abc)
add new disks ( this xyz)
Do healthcheck (...) ?
This would be much appriciated!

That's for new, not for replacements.
>Do you know the start to end procedure
I don't remember if your F class has multiple disks per mag? The output of showpd below would verify.
(I found pictures, it only has one disk per mag.)
If multiple, then you replace them all at the same time with the one servicemag.
If not, you can do multiple servicemag commands at the same time but would be safer to do one by one.
Multiple would put more of an I/O load on the system and lead to possible confusion during replacement.
1) First find your failed disks:
a) showpd -s -failed -degraded
b) showpd -i -failed -degraded
Please post the output of these two commands.
2) Taking the cage and mag info from the above commands:
servicemag start cage# mag#
3) Checking status:
servicemag status -d cage# mag#
4) Once this is done, you can replace the disk(s) in the magazine. Use this to blink the LEDs:
locatecage -t 255 <cage_name> <mag>
(Note: This is a cage name, not number. I.e. cage0.
Warning: Make sure you replace the right magazine and disk!
Make sure you familiarize yourself with the magazine and disk numbering and ordering direction.
5) Then do do the resume:
servicemag resume cage# mag#
6) You can check the status as in 3).
When done, you could do 1) to make sure no more failed disks.
And you could do:
checkhealth pd
You might want to check out the HPGT for F class:
I see a locating a cage here:
Unfortunately the example forgot the time value after the -t. :-(

Re: Replacing disks on 3PAR System (servicemag)
Probably the most simple method would be now to point your browser to the SP and use guided maintenance to replace the disks one by one (wait for the re-balance to finish before replacing the next disk - you may check with servicemag status command).
Hope this helps!
Regards
Torsten.

Re: Replacing disks on 3PAR System (servicemag)
guided maintenance is not an option my friend as we dont seem to have the password :(
plus I always thgouht GM was only to swap disks on the SP rather than the disk in the shelvs ?

Since these are already vacated, hopefully the first part of servicemag will go fast.
The cage and mag for each is:
servicemag start 1 1
servicemag start 1 13
servicemag start 2 5
servicemag start 3 5
For locatecage:
locatecage -t 255 cage1 1
locatecage -t 255 cage1 13
locatecage -t 255 cage2 5
locatecage -t 255 cage3 5

Re: Replacing disks on 3PAR System (servicemag)
Just to be extra sure will this therefore be the steps for asingle disk?
1- servicemag start 1 1
2- locatecage -t 255 cage1 1
3- Remove faulty Disk
4- Add new Disk
5- servicemag resume 1 1
6- checkhealth pd
Then move onto disk 2?
Thanks again!

Re: Replacing disks on 3PAR System (servicemag)
Sounds good. Before doing (3), wait until "servicemag status" shows "succeeded".
Hope this helps!
Regards
Torsten.
