My First Nutanix Lab with Nutanix CE

Today i have completed deploying Nutanix CE in single cluster mode and deployed a 2k8 VM.

I will post further info on AHS troubleshooting / VM Creation /  Nutanix CE installation procedures.

Veeam Backup Replication Setup

As we know Veeam Trending two words enterprise backup tool for VM infra.

Going forward couple of posts will be posted on this tool

I have created a LAB with ESXi host and couple of other servers on my new LAB..

Enjoy. ...

Primary installation :

By registering you business mail id at Veeam you can download temporary licence of Veeam products for 30 Days.

If you are planning a dedicated service account that should be in Local Administrator group of Veeam Backup server.

You can't install Veeam on A domain controller and any other co existing application which uses SQL and IIS.

If you want integrate vCenter , you must have vCenter Login Credentials to  Add the vCenter to Veeam Backup server.

if you want recover Host backup at file system level , you must have host login or host domain account login details.

Hope this help............:)

Database Backups Oracle Recovery through RMAN --------------------DB Backups Part 2

Here is the recovery from RMAN Side. it is as simple as from RMAN side now the big deal how we are going to work with this tool using backup software's, as we all know any integrated backup works through a API to backup in a flexible method.

So when ever we are going deal with any Specific backup we need to know few use full parameters like control file, catalogue, sfile, restore , recover, database, mount, open ,sysadm, etc, etc.

Database Backups Series - Part 1

Most challenging area for any backup tool administrator is Database backups.
Here we are going to discuss most of the database backups like oracle, sql,db2,sap,exchange  starting with oracle I am going to post my understandings on DB backups .

Example of simple rman cold backup in oracle DB:

SQL> CONNECT sys AS SYSDBA

SQL> STARTUP MOUNT;
ORACLE instance started.
Total System Global Area  1.007E+09 bytes
Fixed Size                    65484 bytes
Variable Size              86917120 bytes
Database Buffers          919568384 bytes
Redo Buffers                  73728 bytes
Database mounted.

HP Data Protector ERRORS and Solutions

. HP Data Protector 6.11 Errors & Solutions . . [61:12500] Cannot connect to inet for getting filesystem list on host"clientname.abc.com". . Check for the service on the host. Cannot connect to inet simply indicates that CRS unable to reach client it may be down / service may down/ or firwall stopping the port . .

Emc Legato networker MMINFO usefull TIPS

Here some of use full combinations of mminfo

Generally mminfo resides in /usr/sbin in unix, c:\programfiles\legato\nsr\bin in windows .

To query a client backup info for past 120 Hours:
/usr/sbin/mminfo -avot -c axx.domain.com -t "-120 hours"

some times we can use grep effectively with networker command :
for example above command we can use in alternative way:


/usr/sbin/mminfo -avot -t "-120 hours" | grep -i axx.domain.com

To Query a client backup info with ssid , size of saveset, tape info
mminfo -q "client= axx.domain.com" -r "ssid,name,totalsize,savetime,volume" -t '60 hours ago'

Basic Trouble shooting in EMC Legato Networker

If a client backup failed in EMC legato networker these setups helps you.

# /usr/sbin/ping xxx.abc.com
xxx.abc.com is alive
It is confirms that client is ping able so we can move for second step.

# /usr/bin/rpcinfo -p xxx.abc.com
program vers proto port service
100000 2 tcp 7938 rpcbind
100000 2 udp 7938 rpcbind
390436 1 tcp 9101
390435 1 tcp 8920
390113 1 tcp 7937 nsrexec

By this out put it is confirm that nsrexec running on client.

# /usr/sbin/nsradmin -s xxx.abc.com -p 390113

nsradmin> print nsrla

Above out put may gives the clue about the ip interface and client version which helps you out in trouble shooting.

HP Data Protector CRS Service Errors.

Can not start "crs" service, system error: [1053] 1053 Unknown Error Can not start "uiproxy" service, system error: [1053] 1053 Unknown Error.
Above error happens in Linux , if you miss glib packages. it is known issue with Data protector.

Crs account may not started due to one more reason:
If installation user account password changed it will not start .

PUBLIC & PRIVATE option in backup sepecfication.

If you want to give restore permission other than backup owner or owner group or any user.
we must select PUBLIC option in bakcup specification, this allows permitter user /admin group member to restore backup data.

HP Data Protector CRS Cell Request Service How it works

Hi

Who is the owner of backup ?

CRS (Cell Request Service ) is the owner for all backups in HP data protector. because CRS is the intiator for all backup specifications (Except Some of BAR applications )
Why we add DBA system user in backup admin group ?
Bacause this account acts as CRS for this accounts.

What happens if CRS account is changed and it is not update in Data protector user list ?
No backu will initiated :(

Wish You a Happy New Year

information for device "XXXX_D01"

with loaded medium "abcdef:abcdef:adbcdef:abcedef: KKKLT04"

We can work around the IDB syncranation that depends how your IDB effected.

if it is filenames we can purge expired filenames by omnidubtil -purge -filenames -force.

if you want purge a specified server filenames please see the command usage example.
