One Loop Connection Lost on all disks after move of EVA4100Open in a New Window


We have recently moved our EVA4100 unit from one rack to another, including cabling, and since reboot ALL disks are showing "One loop connection lost" (see attached image)

Is this an issue with the disks themselves or the cabling?

I have read that it can be due to one of the following:

1. EVA not being restarted in the correct order

2. Issue with connection on back of EVA

3. Disks needing to be reseated.

Does anyone know of any steps we can follow to resolve this issue?

Kind regards

HPE FC SN3000B firmware upgradesOpen in a New Window


I need to do dome firmare upgrades from v7.2.x to v8.0.x on a couple of SN3000B switches. Reading through the release notes I can either do this distruptively but in fewer steps or non-disruptively in more steps. To minimise risk I would rather do more steps that are non-disruptive but I want to know if this is truely non-disutptive using this approach. The environment is very simple with 2 x FC switches, a small number of hosts and single storage array. Whereas some hosts are multipathed there are a couple of hosts with only a single HBA port and therefore connected to just one switch. My interpretation of 'non-disrutpive' is that a single pathed host will not suffer any outage when the switch is upgraded - is this what 'non-disruptive' means in the HPE\Brocade world or do I need to **bleep**down any single pathed hosts first?

Thanks in advance


Factors that affect the timelife of a FC diskOpen in a New Window


We have an array EVA P6500 with two controllers. This array was bought in october of 2011.
Recently, we have issues about several FC disk failed (15k rpm). We have five failed disk in the last two months, . This array is not in support contract.
I know that the age is a factor for probability of get a disk fail event, but, my question is:
What other factors can affect the timelife of a magnetic disk, specially in enviroment of EVA P6500 ?I have a similar array in other side with no problems.

Please provide me any clues according your experience.
Thanks in advance.



What is Block Data?Open in a New Window

Hi Friends,

I get the basic understanding of what a block data is, in the sense the blocks are the amount of data stored physically in a hard disk. Is my understanding correct? (I am referring to the context of SAN storage technology). How does it write the block into the disk? Whats the relation with file system and block?

P6300 - Bad cabling configuration detected in the backend devices cabling - 2C4DOpen in a New Window

Hello community,

I recently installed online a new disk enclosure for an already online-upgraded P6300.

Initially they array had 2 disk enclosures. Some time ago I added a third below the others with no issues following the installation instructions.

Now I follow the same steps to add a fourth disk enclosure but it went not that good. Enclosure was recognized with its disks but event log sporadically logs a message like this for both controllers:

***Critical event*** Controller 2 Bad cabling configuration detected in the backend devices cabling. - 0685992d
I've uploaded images with the intermediate 2C3D cabling and the final 2C4D. The initial 2C2D was the same as in the M6625 installation intructions.

No other hardware warnings/alerts in Command View.

Any advice will be appreciated.

Thank you

HP HSV200 SCSI Array DeviceOpen in a New Window


I am new at the SAN configuration, so I need all the help I can get.

I was assigned to install and configura a SAN solution, and I hope I get the most part done. Here is what I have:
- one HP EVA 4100
- two HP StorageWorks 4/8 Base SAN Switches
- one HP DL380 G5 Base Storage Server
- one one MSL4048 LTO 4 Fiber Channel Tape Library

So far, after a huge amount of research I think I got the Switches configured, whit Aliases, and Zones to proper ports. Also, I created Disk groups, vdisks, and hoasts. Now I have to preset the disk to a hoast, but the server does not see any disk.
Looking at a different server, similar configuration as mine (on a different network, not the one I'm in) I saw in Device Manager, for the Disks, the "HP HSV200 SCSI Array Device", which does not show on my server. The only disks I see on my server, are the phisycal disks that the server has.
Could this be just a driver issue? Everything looks good in device manager; I don't have any pop-ups for installing any driver, but I still cannot see the Presented vdisk.
Is there any specific task involved on the server to see the presented vdisk? I just go in Disk Management and rescan for disks after any change I made, but still nothing.
What am I missing?
Any sugestions would be really appreciated.

Thank you

XP7 Configuration reportOpen in a New Window

I am a big fan of the ability to create the configuration report via the "XP7 remote web console". I would like to be able to create this report from the command line (CLI). Is this a possibility? I beleive there was a tool on the older XP's called SANxpert. Is there something similar for the XP7 that a customer can use?

Brocade switch swapoutOpen in a New Window

We currently have a DCX switch with 6 48-port blades that is going to be swapped out for a new DCX core switch in a couple of months.  During this process we will also be migrating the IP addresses for the switch to new subnets.  Due to space constraints I'm going to have to pull the fiber from the old switch, down it, install the new switch, replace the fiber and copy the zoneset to it.  It's been many moons since I've set up a new Brocade, so I thought I'd ask the team if there is anything additional I need to be aware of.

The new switch wil be configured with a different domain ID and different IP addresses on the two CP blades and for the VIP that floats between them.  We will be standing up a new BNA server in the new subnet for monitoring and management.


Any assistance would be greatly appreciated!
