SAN HQ Critical Alert - impossible to get logs from PS4100X

$

0

Hello.

I have a Dell Equallogic SAN PS4100X v7.0.10 and a SAN HQ server in release 3.0.2.7457.

Yesterday I receive an email which talking about error 14.2

Caution conditions:

  • 7/28/2016 5:17:09 PM
    • [ID: 14.2] Unable to establish connection.
    • The SAN HQ server issued SNMP requests at the group, some or all of which failed.  This condition is likely due to network congestion or failed network connectivity.  The server will retry within 60 seconds.  Check your network connectivity and check that the storage group is online.  If the problem persists, contact your Dell support provider for assistance.

If I run SAN HQ Client I can observe a 14.1 Critical Alert: Unexpected Exception in Service. SAN HQ seems to be connected but there is no logs.

I try to upgrade to 3.2.0.8291 but this is the same issue. Nothing change on our side, and I test a snmpwalk with same community, it's working.

Have you ideas ?

Thanks


PS6000xv really poor performace

We have 2 eql 6000XV  1 has been used in production (raid50) for years, and it's been great.  The 2nd PS6000xv is relatively new, from ebay.   I've interratged into the force10 switch and our vmware environment the same exact way as the production ps600xv.  Now that I'm booting up the first VM on it, it feels super slow.  Drive 0 seems to NOT be blinking with the rest of the drives.  it's not the spare.  this is setup in a RAID6.  all drives (minus the spare) will blink in unision during IO operations, drive 0 seems to march to it's own beat ?!!?!  then it will sync up for a bit..  strange, but maybe not relevant.

I have a iscsi connection to a 200gb volume on my local PC. .. just dragged a 3gb file to the iscsi drive.  writes at about 30MB/s ...   dragged it back to my desktop at about 8/MB/s  HOLY cow, that's bad.... I'm 1gb eth,  my previous experious using iscsi on windows was about FULL gb speed... 90/MBs ish.  HELP.

This unit is  out of warranty, but I'm willing to pay the EQL team for some troubleshooting.  any ideas on above issue?

Equallogic HIT Kit and CentOs

$

Hi I am aware that Dell does not support CentOs with the Equallogic Hit Kit.

The older installer used to install on CentOs without issue, out of the box the newer versions do not install, as CentOs 7 fails the operating system check (Although I can persuade it to work).

We are a University and we are highly dependant on CentOs for our day to day operations.

Centos has joined redhat, and to my knowledge the operating systems are almost identical.

Are there any plans to add Centos support in the future ?

How can i put unassigned disk in to the folder 10k?

SAN HQ incorrectly reporting usage errors

$
0
0

We recently had a round of proactive maintenance which upgraded our PS6200 SANs to Firmware V8.1.1 and our SAN HQ to version 3.1.0.7890.

SAN HQ is now throwing error 4.2 (at caution, warning and critical) saying all of the Volumes in the Groups are running at high in-use space levels (varies between 88% and 98% depending on the Volume). Running the Group Manager tool shows that these Volumes are in fact not running at these levels and are well below any usage threshold that would trigger an alert.

I've tried re-installing SAN HQ and re-registering the Groups in it, with no luck. I also tried increasing Volume sizes, which also has no effect. All the Volumes are Thin Provisioned.

Any information or help is gratefully received.

PS5000E hard disk firmware update?

$
0

Hi,

I'm trying to update hard disk firmware on a PS5000E but the following message is given.
 

 
Is there another way to update the firmware?
Inside the tar.gz file I see a file
kit_V7.0_DriveFw_1925749062\dfu\fwdsc\ST31000524NS.dsc
That contains a pointer to the firmware kit_V7.0_DriveFw_1925749062\dfu\fwbin\KD0A.lod
So can I do a "support exec sh" and then run an application to insert the KD0A.lod firmware into a specific drive?
It should update disk8 only (currently ST31000524NS - KD03)
I'm running group firmware V7.1.4 (R405872)

Serjan

broadcom/qlogic npar isoe and MPIO policy on Windows 2012R2

$

Hi there,

I've enabled ISOE on partition 0 in our FC630, broadcom/qlogic 10GbE card. After configured everything on MS iscsi initator then I've seen all the paths were active for a while (10-20min) then one of the paths is just disappeared and never reconnected.

I can see "logout request was received from the initiator" message on the EQL log but that is not very helpful. Interestingly enough, this was just happened to the LUN; I've seen no issue for vss-control. So I was checking out the option and I've noticed that if I change the MPIO from "least queue depth" to "fail over only" then I dont see any path disappearance.

As I'm not quite sure why the default option "least queue depth" is not working, I'd appreciate for any insight and details.

Thanks,

Hello,

I was wondering when taking a snapshot using Dell VSM for vmware is there an option to exclude a hard drive which will be snapshotted.

The hard drive in question would be a page file hard drive which we would not need to recover in the event of failure.

PS6500e Firmware 4.2 upgrade path and best practices

$

recently took over administration of a PS6500E 42 1TB drives, M1000 , PC6224 these units have sat unused for several years. ~5-8  I dont think it was ever used !  Time has been limited to undertake this task, however, I have downloaded and read though lots of documentation as time permits. .

Taking small steps to verify functionality of the hardware was my first priority. 

SIMPLE hardware overview:

> PE R710

> PS6500E

> PC6224

> M1000 w/ 16 blades

< START TESTING>

--> create an account on the Eql support site

--> created an account here!

--> Documented the original config wiring, network topology.

--> All firmware documented on all units ( dont have on hand as I write this aaarg!)

--> re-cabled , stripping everything out and restarting at a know topology. (KISS)

--> Rebuilt head-node R710 with RHEL-6.8.

--> Rebuilt all Blade Servers (16) with RHEL-6.8

--> created user accounts for testing on all systems

--> installed use required SW for development

--> Explained to the users this is the testing stage ONLY

--> Users started testing functionality, ( adding more requirements along the way ! )

--> Explained to the users this is the testing stage ONLY. LOL

--> Users testing functionality, ( adding more requirements, You get the picture im sure)

--> added 144G RAM to the head-node. ( 8G Originally )

--> Added 8TB USB drive for data storage ( user did this ..aarg! )

--> NFS share (8TB USB) from head-node to BS1-16 ( more requirements added )

--> Created test user account on the NFS share /users/home and accessible across all systems

At this point I need to get the PS6500E online ant tested before this monster grow out of control.

I was able to gain access to the unit via serial connection resetting the grpadmin password and running setup via command line. 

I now have access to the GUI and performed some testing to the point of creating and connecting to a new volume via iSCSI to the head node.  

--> Network config overview:

--> MGMT == 192.168.1.0/24 ( IPMI / Dell mgmt?) CMC

--> Compute == 192.168.2.0/24 network comm. head-node and the 16 blades

--> PS6500 / R710 iSCSI = = 10.0.50.0/24 network comm. head-node and PS6500E

--> PC6224 == Have not gained access to this unit, yet.  Seems like a flat configured swx

--> M1000 2 x SWX modules and 2 x CMC modules connected together and 1 cable to the PC6224

--> KVM interconnection works to all nodes ( never use it though )

What is the best path to get the firmware on all this stuff updated and at the current version.  I'm not worried about data loss at this point.  Remember we are TESTING!!!

Thanks for taking the time and I appreciate any help, advise, comments.

Moving member from default pool

$
0
0

I have a group with a PS6210xs and a PS6210x. The x is in the default pool, and the xs is in a different pool. Together, they hold more 26 TB of data, so neither member can hold data all by itself. We also have a new 6210x that I am getting ready to join. I'm hoping to join the new array to the group but not have any data move to it at first, so I have a few questions.

Can the 6210x and 6210xs be in the same pool (setting aside the space issue for a moment)? The hybrid runs raid 6 accelerated, and the other just runs raid 6.

If they can be in one pool, is there any downside in terms of performance?

Coming back to the space issue, and before we join the new array, is it possible to move the 6210x from the default pool to the other pool if the member of the other pool doesn't have enough free space all by itself?

If I can't do that, is it possible to join the new array to the group, but move it to a brand new pool before it starts automatically getting data from the other default pool member?

Thanks.

Error upgrading PS6100 to v7.1.12

I am trying to upgrade a PS6100 from v6.0.11 to v7.1.12. The device has 70-0400 Type 11 controllers. The upgrade fails with "ERROR:30.4.1:Array firmware update from version V6.0.11 to V7.1.12 failed. Reason: The Type 11 controller is not supported by this firmware. See the latest Release Notes for more information.."

The v7.1.12 release notes show the controller to be supported, so I am not sure why I am receiving this error. Any ideas on what is going on or how to get this unit upgraded?

PS5000e member offline - status light indicator light?

$

We have an issue with our PS5000e SAN.  It's not a mission-critical device and we are in the process of moving off of it, but we need to get it back online if possible.

This morning the member went completely offline.  I can connect via web UI, but it just says member offline.  Connecting to CLI indicates the same.  All commands in CLI are executing extremely slowly, and occasionally I get warnings like:   "Logger daemon is losing messages because offline disks are generating more events than the daemon can handle."

Unit is in a datacenter 500 miles away, so I had remote hands send me pictures of it.  One drive shows amber, remaining 15 drives all have green lights, so the failed drive shouldn't have caused it to go down.

show recentevents returns nothing.

On the back of the unit, everything looks fine except for one amber next to a label with a wavy line (possible power issue?).  Picture below:

Before I get too much further with taking action I'd like to know what this light means if possible.

Thanks for any help!


PS M4110 ssh command output

Hi everybody,


I have encountered a weird problem with our PS M4110 series storage. When I ssh into the management console, and issue a command (for example: pool select default show), it returns correct output - an information about the default pool. However, when I send the very same command as a part of the ssh command (for example: ssh grpadmin@1.1.1.1 "pool select default show"), I get - after successful authentication - a message "Unsupported command: pool select default show".

I'm using ssh this way for a very long time with all sorts of devices, and moreover, I have a vague memory this actually used to work even with this particular case. Anybody has any idea what could be a problem?

Thanks a lot

Replication Error

Hi,

I have been happily replicating volumes from one PS4100 to our DR PS4100 in another building for the last few years.

Recently i was asked to create a few more volumes and asked to replicate these also.

When i try to create the replication for these volumes I get the error message "Maximum number of replicating volumes was reached"".

I cannot find anything written about this error message anywhere and I had no idea we had limits for this.

Currently i am replicating 28 volumes at various time intervals daily, weekly or monthly.

Can anyone help me please?

thanks

Jhae.

Using local accounts on FS7600 for SMB Mounts

$

Hi,

I have a Dell FS7600 that I am using for both NFS and SMB shares.  the NFS part works just fine, but I cannot get the SMB mounts to work to any windows servers.

I have not yet added this NAS to my AD, I was hoping to just use local users, but it is unclear where to add them.    Is this possible?

on NFS, the mount must include both the NAS container and the volume, does the windows map have to include both?

Any suggestions would be appreciated.
