Hi all,
I have a hp 3par v400, with 2 discs alerted in the same magazine, but when running the servicemag command I did it specifying a single disk, as shown later, once the process of moving the data of the 2 disks in good condition magazine, perform the replacement of the 2 failed disks in magazine, and when you run the servicemag resume command, an error appears that changes a disk that was not specified by the servicemag command. the question you should ask to recognize the 2 new discs and perform the return of the data to the 4 discs.
The history of the commands performed is as follows.
cli% servicemag start -pdid 32
Are you sure you want to run servicemag?
select q=quit y=yes n=no: y
servicemag start -pdid 32
... servicing disks in mag: 2 0
... normal disks: WWN [2000B4525388DDCF] Id [35] diskpos [3]
.................... WWN [2000B45253CA4315] Id [128] diskpos [2]
... not normal disks: WWN [2000B4525389068A] Id [32] diskpos [0]
.................... WWN [2000B4525388DD54] Id [33] diskpos [1]
The servicemag start operation will continue in the background..
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Here you can see that the command was fine.
cli% servicemag status -d
Cage 2, magazine 0:
The magazine was successfully brought offline by a servicemag start command.
The command completed Wed Jul 10 17:19:13 2019.

Re: Error replacing 2 disc in the same magazine in 3par v400
Hello Jpalma2001 ,
This occurred due to the fact that you had specified only PDID 32 but 2 disks were replaced.
cli% servicemag start -pdid 32
>> The WWNs of 2 disks replaced are as follows ;
... upgrading firmware on pd WWN [2000B45253A8E490]...
... upgrading firmware on pd WWN [2000B45253A9008F]...
>> Hence the system is expecting the original disk in that slot.
What could be tried ?
>> Please try to perform a 'servicemag unmark 2 0'
>> Then 'servicemag start -pdid <PDID disk1 > <PDID disk2>'
>> Once it succeeds run 'servicemag resume 2 0''

SolutionThank you for your response, I followed your instructions and added other commands that led me to success to change the 2 discs that failed the magazine.
The commands performed were as follows.
In my scenario when 2 or more discs of the same magazine fail one must specify the amgazine and not the order of the discs with failure since the servicemag is clear which ones are in normal or non-normal state.
1. servicemag unmark 2 0
2. servicemag clearstatus 2 0 (clean the previous command log)
3. servicemag start 2 0
4. servicemag summarizes 2 0
I hope to be a contribution in the forum.
regards
