Hello amcgill0517
Deleting a Snapshot usually will not take very long. However there some situations that could cause delay the deletion or prevent it.
1. The unit is running at very high capacity, usually less that 10% remaining for the storage pool can slow the deletion.
2. Having the Snapshot mounted and/or being accessing while the deletion is in progress can delay and could prevent the Snapshot from being deleted. In some cases isolating the unit and direct connecting via ethernet may be needed to avoid this.
If none of the above seem to apply, please contact LenovoEMC Support to further troubleshoot and diagnose what is happening.

Losing HTTPS web UI access every day on PX12-400r - known issue?

I have two brand new PX12-400r units that are configured identically and connected to the same physical switch.
One of these units loses the ability to accept connections via the HTTPS web interface. I can still ping it and I can still access it via NFS, but in order to restore web UI connectivity someone has to logon to the console directly at the device and restart the software services.
This box is running the latest firmware available from the Lenovo website. Is this a known issue? Since I have two identical units, I suspect that this one may be defective, but before I ship this disappointing device back, I thought it would be worth checking with others first.

You should contact tech support if this is new, you should have one of the PX12 specialists help.

Delete snapshot subtree fails

Windows 2008 R2 SP1 Datacenter with Hyper-V role installed. OS on drive C. Hyper-V configured to store everything on drive D.
Created a snapshot of a VM prior to installing software update on VM.
Update was successful.
Shut down VM, then in Hyper-V Manager attempt to either Delete snapshot subtree or Delete Snapshot in order to merge.
Get failure message:
An error occurred while attempting to delete the selected snapshot subtree.
<server> failed to remove snapshot.
Have restarted machine and VMMS.
Nothing else I can find online to resolve this.

I usually run into this error due to Anti-Virus.
Make sure that you have set the proper AV exclusions according to the following blog:http://social.technet.microsoft.com/wiki/contents/articles/2179.hyper-v-anti-virus-exclusions-for-hyper-v-hosts.aspx
Hope this helps!

Hi Lucas_Buck,
Did you scheduled any tasks in the Task scheduler at that time?
It is strange that the network caused the Sleep Reason: Button or Lid.
Additionally, there is a large time span between 8/26/2014 5:11:43 and 2/26/2014 3:21:49.

Px12-400r - HDDs and Bays

Hi,
I have three questions about px12-400r:
Question 1:
Is it possible to use 6, 8 or 10 HDD drive bays or a different ammount of 4 or 12 HDDs ? Or other qty different of 4 or 12 HDDs ?
Question 2:
Is it possible to use 4 HDDs with 1TB and 8 HDDs with 6 TB using two different storage pool volumes ? Ex.: Pool A - 4 HDDs with 1 TB (RAID 5) and Pool B - 8 HDDs with 6 TB (RAID 5) ?
Question 3:
The new HDDs WD Drives 6 TB WD60EFRX are compatible with px12-400r ?

Hello lutcardoso
It is possible to have an odd number of drives in the unit. The amount of disks you have installed could affect which RAID options will be available.
As described in the user manual for the px12-400r under Storage Pool Management, you can create multiple storage pools with a minimum of one disk per pool. If you do create multiple Storage Pools, you can assign different RAID types to each Storage Pool. The storage pools can use different types of disks, but within each storage pool you should use matching disk model to help prevent array instability. At the very least matching capacities should be used within a single storage pool.
At this time the WD60EFRX is not officially supported. see here for the currently supported drive list for the px12-400r/450r

Reading SNMP OID for used storage on px12-400r

Hi, does anyone know how get the correct value for used disk space via snmp on the px12-400r nas?
All capacity is configured as one big cifs share. I want to monitor the usage of space with snmp.
If I do a snmpwalk (v3) I can pinout the filesystem /mnt/pools/A/A0 on OID 1.3.6.1.2.1.25.2.3.1.3.38.
If I read the oid for StorageUsed I get a strange negative value: -1084997477
This value changes while data are written to the cifs share so it seems to be monitoring. But what to do with this negative value?
Thanks for any help!

Bios 3.1.1.2908 for px12-400r

Why is information about updating the BIOS hard to find? Link https://lenovo-na-en.custhelp.com/app/answers/detail/a_id/31698
clearly indicated the possibility of updating, but technical support is making every effort that would not help with this issue. Very sad that the old forum was not transferred with all error messages and problems of this equipment. If this information would be more readily available, I would think twice before you order this equipment.

Hi AlexArt,
Have you already inserted the WD hard drives into the px12-400r and tried to boot with them? If the device boots with the WD drives, then the BIOS update is already applied.
If it does not boot, you will need to contact the support team in Russia/Europe to get the BIOS update link and then download it and apply it to your hard drives. You can contact support by clicking on the link below.

Does the px12-400r monitor share free space?

Hello,
We are the proud owners of a LenovoEMC™ px12-400r and are uploading out database backups to it. via NFSv4. My question is wether or not the px12-400r monitors the available space on those shares. I've seen the px12-400r send events before, but nowhere to really see the triggers for the alarms.
Can we get monitoring of NFS shares?
Thank you.
Solved!
Go to Solution.

Hello bogd24
Here is a link for the email notication/alert list for the LifeLine OS Email/Alert List
There firmware does not specifcially monitor the shares and update you on the capacity, however if the volume the shares are located in reaches a point where there is less than 10% free space, you will begin recieving alers/emails about that. The shares automatically expand within the allotted space of the storage volume.
You can set user level quota values than can trigger alerts per user, see the user manual and search for "quotas"
If you would like to officially submit a feature request, please contact LenovoEMC support to have an incident created and sent to engineering for consideration.

cannot destroy 'home/myclone@today': snapshot has dependent clones
use '-R' to destroy the following datasets:
home/test
root@solaris [/] #Why can't I destroy a snapshot? home/myclone is now a volume that is not linked to home/test.
So I would expect to be able to delete the snapshot from myclone.
Maybe I misunderstand something about how this works or I have the wrong expectations.
I would expect a clone to be something like a copy that is independent of the volume being cloned.

The idea is that when you create a clone, it is lightweight and based on the snapshot. That's what makes it so fast. You're not copying every block in the filesystem. So the snapshot is what ties together the parent filesystem and the clone.
For the clone to be independent, you'd have to copy all the blocks. There's no option to do that within the clone process. So as long as both the parent filesystem and the clone filesystem are around, the snapshot has to exist as well.

Merging avhdx files with vhdx files while deleting snapshots

Hi,
We are running one virtual machine win 2012 std. Recently, we deleted the snapshot of this vm in hyper-v manager as the drive space was running out of space. After that, the merging process was running for the VM. Once, the merging was completed, the sql
database running inside got corrupted. Please explain what actually happens during this merging process and how can we recover our db.
Regards,
Anishk

You will need a backup to go back to a valid database.
Snapshots are not supported in Production and cause in few cases issues and behaviour like you are encoutering now.
You have to avoid using snapshots in production, snapshots are nice and they unction propely in 99% of the cases. You were not lucky. If you want to use snapshots with a VM for a reason (test update or a new configuration), backup your VM before.

How to purge PERFSTAT.STATS$SQLTEXT table, after deleting snapshots

I had an alarm on the free space of the PERFSTAT tablespace. In order to free up some space I tried to delete some old StatsPack snapshots, with the following query:
DELETE from perfstat.stats$snapshot where snap_time < sysdate - 10 ;
COMMIT;
After running it the space usage on the tablespace was not significantly reduced. I checked again and I saw that the table PERFSTAT.STATS$SQLTEXT was very big, almost 8 Gb, but all the other tables were a lot smaller. I read somewhere that the sppurge.sql procedure, that comes with Oracle, could be used to purge the statspack data, but that it comes with the lines related to PERFSTAT.STATS$SQLTEXT commented, because it is a big query and it can take a lot of undo space. I tried to run the followiung query, which I found in the forum, by Don Burleson, but it failed, because of running out of undo:
DELETE /*+ index_ffs(st)*/
FROM perfstat.stats$sqltext st
WHERE (hash_value, text_subset) NOT IN (
SELECT /*+ hash_aj full(ss) no_expand*/ hash_value, text_subset
FROM perfstat.stats$sql_summary ss
WHERE snap_id NOT IN (SELECT DISTINCT snap_id FROM perfstat.stats$snapshot)
COMMIT;
Is there any way to know if the PERFSTAT.STATS$SQLTEXT table has records that could be purged, and an easier way, that don't use as much undo, to purge it?
My oracle version is:
Oracle9i Enterprise Edition Release 9.2.0.7.0 - 64bit Production
PL/SQL Release 9.2.0.7.0 - Production
CORE 9.2.0.7.0 Production
TNS for Solaris: Version 9.2.0.7.0 - Production
NLSRTL Version 9.2.0.7.0 - Production

Is there any way to know if the PERFSTAT.STATS$SQLTEXT table has records that could be purged, yes, just transform Delete to Select
SELECT /*+ index_ffs(st)*/ count(*)
FROM perfstat.stats$sqltext st
WHERE (hash_value, text_subset) NOT IN (
SELECT /*+ hash_aj full(ss) no_expand*/ hash_value, text_subset
FROM perfstat.stats$sql_summary ss
WHERE snap_id NOT IN (SELECT DISTINCT snap_id FROM perfstat.stats$snapshot)
and an easier way, that don't use as much undo, to purge it?yes. do it smaller chunks
BEGIN
LOOP
DELETE /*+ index_ffs(st)*/
FROM perfstat.stats$sqltext st
WHERE (hash_value, text_subset) NOT IN (
SELECT /*+ hash_aj full(ss) no_expand*/ hash_value, text_subset
FROM perfstat.stats$sql_summary ss
WHERE snap_id NOT IN (SELECT DISTINCT snap_id FROM perfstat.stats$snapshot)
) AND ROWNUM<=10000;
EXIT WHEN SQL%ROWCOUNT = 0;
COMMIT;
END LOOP;
COMMIT;
END;

Hyper-V DC delete Snapshot

Hello Community,
Server DC1 ( 2012 DC) , there is another DC2 (2012 DC ) in Domain, should be exported from one Hyper-V (Server1) and imported to an another Hyper-V (Server2).
Problem is that DC1 has two snapshots. Deleting the snapshots causes that the highestCommittedUSN will be increase very high. Could the Export inport be done without deleting the snapshots?
Is there a better way?
Thx

Hi ,
I assume that both hyper-v servers are windows 2012 server and all of the VM files are in a single folder , you may try to shutdown the VM and stop service "hyper-v virtual machine manager" then
copy the folder to "server2" to import it directly .
"In Windows Server 2012 virtualized Domain Controllers, you can now restore snapshots without permanently damage domain controllers.
While this does not prevent other issues for other technologies and applications, it does make domain controller virtualization safer."
Based on my understanding , merge snapshots will not damaged domain controller since server 2012 .
For details please refer to following link :

E-mail notification does not work. Test message fails, like everyone else. Is that possible? Someone else had this problem?

Hello gusev67
Have you tried with/without custom email notification (SMTP) settings?
Have you checked if the defaut or custom SMTP port has been forwarded to your px12?
Have you checked if your ISP is blocking SMTP ports for your connection?
