Thanks
about what i have application run , ihave these:
domain Server
exchange Server
Vcenter
Students Information System (web application) apache Server
Oracle Server
i have aslo some service like file sharing don not matter
what is important is the apache and oracle Server
Regards
I would suggest to keep two important application in two different Pools so that dedicated Controller CPU and cache should take care of the performance.
Hope this helps!

Thanks You
please another question
what the kind of Raid you prefer?
raid 10 or raid 5??
thanks you
RAID10 always better in terms of performance compare to RAID5
There could be many comparison but you can consider below,
"RAID10-> It offers fantastic performance for random reads and writes because all operations occur in parallel on separate physical drives.
RAID5-> It also offers great read performance because of striping. However, writes are slower because of the overhead of calculating parity."
Hope this helps!

We added the 5 disks on friday bays 16-20, and we had some issues with the controllers going offline.
Manage to restart the controller, and configure the 4 out of the 5 as dedicated spares.
We did the "trust" command and the volume came back online and it did a reconstruct momentarily. and it went offline again.. It now showed RAID set 4 -> 16 only - previously is was disk 11.
We did the trust" command and the volume came back online and it did a media scrub.
It all shows online now and configured as follows :
vDisk1
RAID set 1-> 1,2
RAID set 2-> 3,5
RAID set 3-> 8,10
RAID set 4 -> 11, 16
vDisk2
RAID set 1-> 6,14
RAID set 2-> 12,15
According to the previous logs, they have been issues wth Disk 8 and 11, but at moment, its showing all green, ticks vdisk is online and health status "ok".
Whats the best next steps, I am worried disk 8 and 11 may fail together? Is they any commands I can run to do a check on the disks?
Also, is it better to configure as dedicated or dynamic spare?
Thanks.
Nice to hear that we are able to recover back the vdisk. It was not easy without checking logs but thanks for your co-operation to made this possible.
Now regarding drive health state, only option is to check logs and find if any hardware error exists or not.
If 8 and 11 went down together but still your vdisk will be up and data can be accessible.
Real challange will be when you have both drives failure from a same sub-vdisk or RAID set.

Hello.
We have a similar problem. I tried turning the controllers off and on, but I can’t connect using any interface (https, telnet, ssh). However, all works, the hosts see the mapped drives.
Error: mccli: error while loading shared libraries: /app/lib/libFWcust.so: cannot read file data: Input/output error
Hi,
Thank-you for your help, without this I would have been completely stuck
I ran a vdisk verify overnight, and as suspected it has shown errors on disk 8 & 11 :
An error was detected by a disk drive. (disk: channel: 0, ID: 7, SN: 6XR1xxxxxxxxxxxxx, enclosure: 1, slot: 8)(Key,Code,Qual:0x1,0x17,0x1)(CDB:Rd 03bf6280 0040)(Info:0x03BF629A)(CmdSpc:0x11201100, FRU:0x0, SnsKeySpc:0x800001)(Recovered Error, recovered data with retries)
An error was detected by a disk drive. (disk: channel: 0, ID: 10, SN: 6XR1MAKxxxxxxxx, enclosure: 1, slot: 11)(Key,Code,Qual:0x1,0x17,0x1)(CDB:Rd 00239e80 0040)(Info:0x00239EBC)(CmdSpc:0x11201100, FRU:0x0, SnsKeySpc:0x800001)(Recovered Error, recovered data with retries
The RAID is still in a healthy state - whats the best way to replace the drives?
Thanks
Hi,
I have also had similair issues, where I cant log in to the gui with correct creds on controller A.
We have 2 controllers on our MSA, and I managed to login into controller B and restart the management on "A" and it worked.
If you still cant connect, then the controllers are "too busy" to process your request - try logging in when then is less I/O going on maybe?
Yes you can go for proactive replacement instead of waiting for those drives to fail but I would suggest 1 drive at a time.

Hello ALL,
my MSA2050 is composed of 11 disks (1,2 TB raid5 and two spares) as a result of 2 volumes 4399,9 GB each one; first one has allocated 277 GB and the second one 1966,3 GB, so there is enough free space and all operation seem to be right.
But, if I take a look to MSA2050 home page I can see as "Acailable Storage" 0.0 MB, why this result ?
Regards
Alberto
Please share the SMU home page screenshot. It will be good if you can mark the area where you are getting Available Space Zero MB
Also please share the below outputs,
show pools
show disk-groups
show volumes
show drives
show snapshots type all
show snapshot-space
Hope this helps!

Here are details:
Actually I was looking for "Capacity Information" from the Home Page screen.
You can go to Home Page and below of the page you can hover your mouse pointer and Capacity Information will pop up. Please share that information.
As per my understanding "Available Storage" which you see as 0.0MB now will be same as "Unused" in "Capacity Information".
As per CLI outputs it's clear that you have approx 7.3TB space left.
Hope this helps!

Thank you so much for you help..
Could not have done this without you.
Many Thanks.
Here are capacity information:
I think this looks OK.
There is all capacity allocated to the pool, there is no unused space.
Thank you for your support !

Alberto
