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?
I have some vdisks on a EVA P6350 under the command view we don't see the presentations hosts.
under the utility SSSU we see this hosts. the firmware of storage is XCS1300000 and the version of CV 10.3.3 ;
on others vdisks we see hosts. we reboot the manap and the pb leave.
any suggest please
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
We have an array EVA P6500 with two controllers. This array was bought in october of 2011.
Please provide me any clues according your experience.
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?
What type of Fibre optics cables available(Single and Multi Mode)? I would like to understand the distance, speed limitations. I am very much new to SAN technology, hence wanted to understand how it works. Also how can we achieve a fibre optic cable connectivity between 2 Data Centers separated by 100-500KM?
I am new to EVA diagnostic. And I have a question about the navigator step 1: create the workspace
First, I need to create the workspace. but after the creation. It indicates could not open the workspace. Anything wrong? Just feel so wired about the software......
Because we StorageWorks Command View EVA 9.3 problem, we want to re-install, but no source, I would like to ask the website can tell me? Thank a lot
In the company I work in they have the following HBA:
The firmware is on 10.6 however in the revision history it jumps from 10.5 - 10.7 does anyone know if 10.6 was pulled for any reason? The OS is Linux 6.4 running on a Brocade Director on v7.4.0b.
The link i'm looking at for firmware is:
Any help is apprecatied because if its been pulled it had to have been for a reason. Keen to find out why!
Before there is no problem, today found a connection license error, do not know what the problem is a Windows 2003 Server, recently updated hotfix, do not know if this is caused? Can help? Thank you
OS : Windows server 2003 R2 64bit
CommandView version : v9.03.00.100811
I'm trying to present Vdisks to a linux box but with no sucess.
Vdisks are created and presented to Host. At host level (Red Hat 6) after executing hp_scan, fdisk is only showing local disks.
These are brocade configurations:
zone: RDP 102,0
364549-005 HP FC System I/O E-PBC Modul-A EVA5000
without HSV? What will happen when I connect this to Windows/Linux server?
No other hardware warnings/alerts in Command View.
Any advice will be appreciated.
I need the cabling diagram of EVA 8400 hsv45 2C8D
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.
We have a P9500 connected to the ESX systems.
On the official HP website is the new release of xpinfo/p900info which should be supported on VMware.
But it does not work.
Someone has got to try it?
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?
how to change the status of the disks:
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!
We are facing a critical issue with our HP EVA4400 SAN Storage, we shutdown our EVA for electricity maintainance then when we powered on the EVA again, we couldn't access the management module or even the console ports, no connection between the storage and the FlexFabric module and we can't reach the data than on disks! , so any luck to solve this issue?
