Navisohere: cannot create raid group: SPA: Array Microcode error

A little more information would be helpful:

1. Which version of flare are you running (base code on the array)?

2. Are the six ATA disks free (not already in a Raid Group)?

3. Where are you getting the error? During the "Create Raid Group" windows or after?

4. Has there been a flare code upgrade recently? Was the software committed?
4a. check the Software Properties page and see if there are any packages that need to be "committed"

1. Which version of flare are you running (base code on the array)?
2.19.300.5.019

2. Are the six ATA disks free (not already in a Raid Group)?
yes they are free. by the way, i have added them recently to the enclosure.

3. Where are you getting the error? During the "Create Raid Group" windows or after?
iam getting the error after i select the disks for my raid group when clicking apply as the last step.

4. Has there been a flare code upgrade recently? Was the software committed?
4a. check the Software Properties page and see if there are any packages that need to be "committed"
no upgrade has been done, and yes the running FLARE code is committed.

hi,

i forgot to mention that i have created a 1 T LUN before on the ATAs then i unbinded it and destroyed the RAID group. then i tried to recreate another raid group,and the error appeared.
please provide suggestions as soon as possible.

its not clear to me...
if you have moved the disks while RAID groups were bound on them, that causes issues..the disks should be unbound before you can move them between arrays.

if you moved disks by unbinding them, were you able to delete the RG succesfully or was there any error?

if you see latest sp logs, are there any "CRU Signature errors"?

i have moved one drive by another, but i did managed before to create a raid group on them a create a 1T LUN and it worked fine. but after removing them, and tried to create another raid group, its giving me this error

well, here is a description of what is going on:

i had an ATA enclosure having 5 disks ( 0-4 ). then we upgraded the storage and added 6 new ATA drives to the enclosure.

both new and old disks have exactly the same properties regarding the capacity and the speed.

whenever iam including disk(4) with the new disks for creating a RAID Group its giving the mentioned error. so, what i did is that created successfully a raid group of disks 5 to 10. then i tried to make disk 4 as a hotspare but still the sma eroor occurs.
hope this information might help

okay...so you have a set of old 5 and new 6 disks on this enclosure.



what if you create a raid group in old set, are you able to do this? Earlier you mentioned that you are not able to create rg on 6 disks...were those the new set of disks? i felt something contradicting.

if you are not able to combine disks from between these sets, maybe the firmware present on the disks itself has some issue.


Can you upgrade the code? path 19 is quiet old code i believe. latest patch should be 40. upgrade to patch 30 atleast since it had some upgrades for ATA code.

Disks 0-4 are part of what is referred to as the OS disks or Vault drives. Disk 4 (the fifth disk counting from the left) is where we store the recovery images for the OS.

When you use any of these disks (0-4) with other disks in the enclosure, you get slightly less available space (the space that is reserved for the OS/Vault functions) on all the other disks. You can not use disk 4 as a hotspare.

Disk 4 may be down on one-side of the dual bus - try issuing the following command from a DOS prompt from within the c:\program files\emc\navisphere cli directory:

navicli -h IP_Address_SPA get disk 0_0_4 -state
navicli -h IP_Address_SPB get disk 0_0_4 -state

The "state" should be "ENA" for both sides - if one side is different, say PUP (powering up), then the disk is stuck and may need to be reseated (this does not always work).

If the above is true, the lights on the disk will be green and amber - which I assume you've already looked at.

Rami said that these were ATA drives....Does EMC support putting FLARE on ATA Drives? He never mentioned what Bus or Enclosure this was either.

Thats what I thought. In either case, Vault or FLARE are irrelevant to the issue posted here.

Thanks Allen

I'm pretty sure you are right about this one.

The FLARE drives can't be ATA, so this has to be something other than Bus 0 Enclosure 0

yep, and even if trying to create a RG from vault drive and similar sized non-vault drive, there isnt any error, only the RG would be a bit smaller than usual.

for the ATA enclosure, surely it is the first one. the first one is a FC enclosure. the second one in my CX300 is the ATA one and we have the 3rd enclosure as FC.

i usually do not recommend to create Raid Group on disks 0-4 form the 1st enclosure for the reasons you mentioned.

so, still i have to run the commands you gave me.

I was not real careful when I read the original post - no, ATA disks are not supported as flare disks (first disk enclosure) except on the AX series and now the new CX3-10c.

The navicli commands may help in derermining if there is a disk problem - if there is, probably best to open a service request.
