Emc Grabs Procedure Essay

This script is provided as a means to collect system and/or software configuration for investigations by EMC. To Install : Extract the tar file into a suitable directory using following command, command: tar -xvf emcgrab_<os>_<version>. tar Please ensure that your filesystem has at least 500M free of disk space for temporary files that may be generated during its processing. If running ECC 5. x the resulting tar file could be very large. Please NOTE: 1. The script will prompt the user with a warning message hould it detect less than 25M remaining on the file system every time the script runs the file system check routine. Each time the user will have the option of continuing or aborting the script. 2. The script will prompt for EMC license agreement even in autoexec mode. Once EMC license agreement is accepted then it will work as usual for autoexec mode. Operation : The script should be run as user root, to prevent any data not being collected through lack of permissions. The scripts defines a PATH environment based on the default installation paths of it’s software.

If these are different, some modules may not work. It is possible that some commands could run for a lengthy period. Each module has a max runtime limit, ranging from 60 seconds through to 450, depending on the module. The script will generate a compressed tar file, residing in the outputs directory. Its format will be ‘<hostname>_YYYY-mm-dd-hh. mm. ss>_<OS>_emcgrab_<version>_[full | lite]_CC<Request Number>. tar. <Z|gz>’ depending on whether compress or gzip has been used as their compression utility.

If no Request number is defined, ;CaseNo; will default to 0000000000 Syntax : ./emcgrab. sh [-h] [-v] [-o options,options] [-autoexec] [-backup] [-clariionIP ;IP Addresses;] [-ip] [-ipmask] [-legal] [-lite] [-nomsg] [-nw] [-OUTDir new_output_directory] [-quiet] [-symmid bypass|prompt] [-vxdmpdebug] where -h : Displays help screen -v : Displays version information -o : User defined options, Comma Separated List (See below) -autoexec : Bypasses user interactive prompts (but will prompt for EMC’s license) -backup : Bypasses interactive menu, when scheduled via cron. clariionIP : Comma separated list of IP addresses for SPA / SPB -ip : Comma separated list of IP addresses for SPA / SPB -ipmask : Will mask the ip address of the host in all the files collected in the EMCGrab -legal : Bypass the showing of Legal Notice and asking the user to accept it. If this switch is specified it means user automatically accepts the EMC’s license agreement -lite : A reduced subset of data collection that is required by HEAT analysis server -nomsg : Will not collect the messages logs nw : Collects Networker related information on AIX, HP-UX, LINUX ; SunOS -OUTDir : Option to store final EMCGrab file at specified location -quiet : Suppress all status messages -symmid : bypass|prompt – Bypasses Symmetrix or prompts for each Symmetrix detected -vxdmpdebug : Runs vxdmpdebug script with ‘Y’ option enabled Options : This is a comma separated list of additional modules. By default these options are not run, and need to be invoked by the -o syntax. Supported Optional modules are as follows :- : clariion – Must be used with -clariionIP ;SPA,SPB; dru – Collect data relating to the EMC Open Migrator/LM (DRU) : ecc – Collects configuration and log files for ECC 4. x / 5. x. : erm – Collects data relating to EMC Replication Manager (Autorun) : hacmp – To collect log files relating to AIX HACMP cluster. : ifs – Infomover File System : ift – Infomover File Transfer : im – Both ifs and ift modules : inq – Perform SCSI inquiry against devices (automatic detection) : pp – PowerPath (automatic detection) : ppvm – PowerPath Volume Manager (automatic detection) : sc – Sun Cluster 3. 0. : sdmm – Symmetrix Data Mobility Manager se – Solutions Enabler (automatic detection) : svm – Solaris Volume Manager (automatic detection) : vcs – Veritas Cluster Server. : vxvm – Run Veritas Volume Manager (automatic detection) : rp – To collect logs on Solaris ; AIX in Recover Point Environment : networks – Collects data relating to Devices attached to Host (automatic detection) OS Support : This version of EMCGrab is tested and supported on the following Operating Systems : Solaris 7 or later : AIX 5. 1 and later : HP-UX 11. xx or later : Tru64 4. x or later (OSF1) : RedHat Linux 7. x or later : RedHat Advanced Server 2. or later : SuSE Linux 7. x or later : Irix 6. 5. x or later : Siemens Reliant Unix 5. 4. x or later During normal operation, it is possible that some commands will report “Not Found”, as the command file contains all commands for each OS and application release. This is normal. Host : HP-UX If BCV and / or RDF2 devices are presented to the host and they are in a ‘Not Ready’ state, then ioscan may timeout. Module Support : Module : clariion (Clariion Storage) Automatic Detection : AIX, SunOS, HP-UX and Linux This requires Navisphere commands to be installed on the host platform.

The IP addresses will be automatically detected for any SP where devices are visible to the host. You can define additional IP addresses through the use of the -clariionIP command line option Module : dru (EMC Open Migrator/LM) (Optional) Runs stormigrator commands, lists configured sessions and collects logs for last 14 days. No known issues. Module : ecc (EMC Control Center) (Optional) Predominately configured to collect ECC 5. x information. Module: erm (EMC Replication Manager) (Automatic on AIX, HP-UX, Linux and Solaris) Collects ERM data. No known problems.

Module : hacmp (AIX HACMP cluster) (Automatic Detection) Only collects log files. Module : ifs (EMC Infomover File System)(Optional) Collects configuration and log files for last 14 days. No known issues. Module : ift (EMC Infomover File Transfer)(Optional) Collects configuration and log files for last 14 days. No known issues. Module : im (EMC Infomover)(Optional) Runs both the ift and ifs modules above. No known issues. Module : inq (Automatic Detection) This is run by default to assist with automatic detection of Clariion, Symmetrix and third party Storage Arrays

A gatekeeper device should be visible to the host, for communication to the Symmetrix. The script will attempt to check for the existance of a gatekeeper, and it this check fails, you will have the option to abort the remainder of this module. Some commands may not return any output, depending on whether the relevant Solutions Enabler license has been installed.

Sending the report file to EMC: Once you have created your report file you need to send it to EMC Customer Service for analysis.

This is done easily and securely using EMC WebSupport. Go to WebSupport Case Management (Note: You must be a registered WebSupport user. Select the registration link to register) For a new support case select ‘Create a Case’ and complete the simple step-by-step creation process. Once you submit your case you will have the opportunity to upload your EMC Grab file to your case using the ‘Attachments’ functionality. For an existing Support case, locate your case by using the ‘Quick Case Search’ or ‘My Open Cases’ portlets or by using the ‘Case Query’ functionality in ‘Case Management. Select the ‘Attachments’ tab and upload your file. Note: You may also use EMC’s ftp site if WebSupport is not available. Contact EMC Customer Service for more information. Uploading the report file to HEAT You may also upload the report file to our HEAT server for analysis. The HEAT server can be accessed through PowerLink Home ; Support ; Product and Diagnostic Tools ; Environment Analysis Tools ; Host Environment Analysis Tool (HEAT) or directly to https://servicetools. mc. com (a PowerLink account is required).
