I want to convert two Raid 5 VDisks to Raid 6. One of them by adding an additional Disk, the other by converting it. My questions would be, is it possible to convert an existing Raid 5 VDisk to a Raid 6 VDisk, without loosing the Data? And is it possible to convert the other Raid 5 VDisk to a Raid 6 VDisk, by adding an HD?
Thanks and Regards,
I am thinking of purchasing 2x HP D2600 Dual SAS Controller Expansion Storage Array (AJ940A) will they work with HP P2000 Dual I/O LFF Drive Enclosure Chassis (AP843A ) with 2x HP P2000 G3 10GbE iSCSI MSA Array Controller (AW595A )
Can't see it in the quick spec's
We are looking for a SAN to be the backup repository on premise.
-Capacity 15TB to start and ability to grow. -Put an identical unit in a colocated offsite location. -SAN's should de-duplicate and stay sync'd overnight (this has to be a (preferably) built in feature of the SAN). I am looking for the products that is optimized for this WAN syncing.
We also want to explore, moving production data into the WAN from the current Direct Attached Storage in 6 Windows 2008 R2 Guests (running in 2 VmWare physical machines), total 2 TB; and 2 Ubuntu 16.x physical servers, total 11TB. What kind of performance can I expect from a SAN compared to a DAS 10k NAS Raid 5 system
Hi, I'm a new owner of MSA 2040 iSCSI. Actually I have configured two virtual volumes in a single virtual pool assigned to controller A. Now I would like to test high availability before production. Can I hot remove controller B for some minutes (for simulate a controller failure) and then reinsert it without issues or is best to avoid this operation? There is some actions or reconfigurations to do after this test?
Thanks in advance
I am hoping someone can clarify some points based on sales information we were given from a supplier.
We are yet to purchase this product.
We have been told that with 2 nodes we can expect 12TB of usable storage?
We have been told that the data will be live on both nodes for speed and data protection.
I am unsure how the above is possible? If one node was lost there would only be 7.5TB of disks available? How would 12TB be able to exist still? Something must be lost?
Can someone help clarify the above and aid my understanding of the system?
Hi, we have a MSA2040 FC, with performance tiering license, running software GL220P009, the latest when writing this post. Connected are two Windows Server 2016 Datacenter Hyper-V hosts in a failover cluster, both connected with dual-port HP 8Gbps HBA's in a MPIO setup. Everything works fine from that perspective, and the whole setup is 100% verified with HPe SPOCK. When I do sequential operations, because of MPIO I can do about 1400MB/sec of traffic. Not bad.
When we bought the unit 2 years ago our representative told us ODX would be available through a forthcoming update (that's about 3 years ago now). We've never got ODX running under 2012R2, but now with 2016 I'd though to give it another try, but alas, no cigar. Neither can I find any official information of ODX being supported or not.
One issue I run into is that we deliberately use fixed VHDX files on our VM's. Whenever I expand a disk with let's say 100GB, for some reason it only does that with about 200MB/sec and an insane amount of IOPS, stalling practically all other IO. While that's more of an OS issue than SAN issue by itself, ODX should fix that.
So I'd like to get some additional information on how or when ODX is supported by the MSA2040. No-one seems to be able to tell me. Has anyone got it working?
Good afternoon, all!
Our company is looking at an MSA 2042 as a replacement for our current SAN array. For the community: how is the management on this beast? There's only one of me and I'm sliced pretty thin now. LOoking for ease of management, accurate reporting and alerts, integration with my current vSphere 5.5 and up environment, and reliability.
Thanks for any input you all have on these!
Where can I find Infos about Harddisk compatibility with our MSA2324sa? I tried to find a Data sheet or any other Info about the system, but it's not easy at all...
Thanks and Regards,
i forget my password .
who to change or reset password hp san MSA 2040?
We have an old MSA2324sa and since 01.01.2017 a problem with two disks. The errors are in the attached .jpg!
Could somone help me with this? Let me know what info you need and how to find them. I'm an absolut beginner with Storage systems.
Thanks and Regards, Rico
I have a p800 controller which is plugged into 2 MSA60 appliances.
I understand that the drive size limitation of 2.2TB is determined by the controller. What would be a controller I should move to that would still allow me to use the MSA60 appliances?
I want to discover the HP SAN p2000 device (LUNS, Disks details) using API. Is there any API to get these details.
We recently removed a virtual Hyper-V guest, from our server infrastructure, and also removed the vFC adapter from the virtual machine.
Afterwards ive tried to delete the 2 hosts in the HP P2000 G3, but were only allowed to remove one of the host profiles.
When trying to delete the last host profile from the Web GUI, we receive an error: "The command had an invalid value (xxxxxxxxxxx) - Host was discovered, so it cannot be deleted"
From what i could read from other forum posts, we have to delete it through CLI.
When trying to delete host in CLI (delete host VMname-P1), we receive an error "The command had an invalid value"
What is the correct way to delete the discovered host, which no longer exists ?
Thanks in advance.
Can I update a disk firmware online on a MSA2012fc ? I suppose it's not a good idea if the disk is part of a Vdisk, but if its state is "AVAIL" , out of any Vdisk, is it safe update it online? Coud this procedure be unsafe for the concurrent I/O transactions at the Vdisks?
Thanks in advance for any help.
Hi, I'm experiencing poor write performance on a MSA 2040 with 8 disks, configured as:
We have a HP MSA1000 with 2x MSA30 disk shelves and 1x256mb cache controller. We are unable to see the disks 8-14 on both of the MSA 30's but can see 1-14 on the MSA1000 itself. Can anyone help us see the other disks?
I've created 5,2 TB volume on MSA2040. ESXi host can see this storage device (LUN) but it recognizes it's capacity as 4,66 TB. How it is possible? Where is 500 GB?
Thanks in advance!
We have hp p2000 g3 storage with RAID - 6 configuration (12 HDD=12 *2TB=24TB)
we got a problem ,
1). 1 HDD is failed then we replaced new HDD (11th)without any configuration means now it showing AVAIL
2).We mistakenly removed and reinserted another HDD(9th) at the same time ,after its showing LEFTOVER disk.
Here, 11th HDD showing no indication but 9th HDD is showing Ambler .
what can i do We have 24 TB data.? What troubleshoot i can do ? please suggest onthat..
I'm having trouble with SAN Switch and VMware. The situation is as follows. I have 2x HP MSA SAN Switch 32port, 2x servers, 2 SANs storage (IBM, HP). Both servers see both storages. It's okay. Now, I want to add additional third server, but this one cannot see the storage. I think that zoning in the switch I set properly, but it does not work. Topology is placed in the attachment. According to the diagram, I think that second switch is used as a backup if first stops working. Both switches are set to the same (except WWN of course), the same aliases, same zoning. Aliases are set far more than are actually connected devices (many servers in the server room are not already there). Just 3. So I deleted on one switch settings (aliases, zoning ...) and set new, but it does not work. Added third server sees only HP Fibre Channel RAID array controller. But no HP/IBM storage. And it is interesting that when I deleted one switch, so the two servers still see storage at both FCs, while I think that one side should disappear. Screens from Vmware are in attachments.
I picked up an MSA 60 as a cheap backup target. When I power it up, it just emits a high pitched tone, like a bios error, that doesn't stop. The seller says this is normal, but I have some other MSA models and none of them do this.
Does anyone have experience with these units and can tell me if you just hook up power (no SAS cables) does it emit a tone?
