Hello lmendesbz,

Here is a link to a KB that maybe of assistance.  https://dell.to/36j87Ad

I tried to enable write caching, but the error below appears.

All LUNs write cache are enabled.

Hello lmendesbz,

Which SP is the default owner of the metalun and which SP currently owns the metalun?

I did trespass the LUNS to SPB. The ML4 is working on this SP. 

C:\Program Files (x86)\EMC\Navisphere CLI>NaviSECCli.exe  getlun -trespass -name
LOGICAL UNIT NUMBER 201
Default Owner: SP A
Current owner: SP B
Name ML6

LOGICAL UNIT NUMBER 213
Default Owner: SP A
Current owner: SP B
Name ML1

LOGICAL UNIT NUMBER 200
Default Owner: SP A
Current owner: SP B
Name ML3

LOGICAL UNIT NUMBER 206
Default Owner: SP A
Current owner: SP B
Name ML2

LOGICAL UNIT NUMBER 12
Default Owner: SP B
Current owner: SP A
Name LUN 12

LOGICAL UNIT NUMBER 211
Default Owner: SP A
Current owner: SP B
Name ML5

Hello lmendesbz,

Is SPB the default owner of ML4? I don’t see ML4 listed in the screen shot that you provided.

Yes! It is. 

Hello lmendesbz,

Have you run a battery test since you replaced your SPS?  Have you rebooted both SP’s?

Hey you! 

I've reload the both SPs. About baterry test i didn't. 

Hello lmendesbz,

I would run a battery test and wait for it to complete.  You can also try to restart unisphere management server.  Here is a link that explains how to do the restart. https://dell.to/3wHFaZD

So, I did the battery test and no erro flag. About restart the Management Servr I've looked at tutorial  and it isn't clear where is the button "Restart Management Server", do you know where is? Or a away to do it by Naviseccli ?

The Unisphere is the 1.2.27

Hello lmendesbz,

Here is a link to a KB that explains how to do the reset via cli.  With using that old version of unisphere there were fixes in newer versions that resolved this issue.

I reloaded th managers but it didn't work. Looking more closely I saw that the faulted ML components are in BOUND UNS or TRANS status.

ML1 L1 BOUND UNS RAID 0
ML1 - L2 BOUND UNS RAID 1 (EF)
ML2 - L1 BOUND UNS RAID 3 (EF)
ML2 - L2 BOUND UNS RAID 4 (EF)
ML2 - L3 TRANS RAID 5 (EF)
ML3 - L1 BOUND UNS RAID 3 (EF)
ML3 - L2 BOUND RAID 4
ML3 - L3 TRANS RAID 5 (EF)
ML4 L1 BOUND RAID 3
ML4 L2 BOUND RAID 4
ML4 L3 TRANS RAID 5
ML5 - L1 BOUND UNS RAID 0 (EF)
ML5 - L2 BOUND RAID 1
ML6 - L1 BOUND UNS RAID 3 (EF)
ML6 - L2 BOUND RAID 4
ML6 - L3 TRANS RAID 5 (EF)
ML7 - L1 BOUND UNS RAID 3 (EF)
ML7 - L2 BOUND RAID 4
ML7 - L3 TRANS RAID 5 (EF)

Hello lmendesbz,

Based on what you posted it is best to call into support to resolve this issue.  You can try to power the system all the way down then, power it back on & it may resolve your issue.  However, if you have any data that you don’t wish to use then I would open a support case.
