Re: How to release Configuration lock Saurabh Rohilla Mar 16, 2011 4:11 AM (in response to StuartA58) Hi,If its happening regularly that config lock does not get released on its own check over here
Useful commands in troubleshooting the issue fcinfo hba-port cfgadm -lao show_FCP_dev powermt display powermt display dev=all powermt display paths sympd list syminq hba syminq -wwn syminq -pdevfile symcfg list emc, flag, symmaskdb -sid 1234 -wwn xxxxxxx list devs : List the devices masked to the given wwn number . or does it load into the memory of each of the components described above?? create dev count=4 size=2000 emulation=CKD-3390 config=2-way-mir attribute=CKD-meta; PAV aliases are used to allow multiple concurrent access to mainframe devices. browse this site
If you want to know what is going on under the covers, then physical disks of the same physical type, RAID configuration and performance characteristics are combined into Disk Groups. This must include at least 4 meta devices. This command start sync between R1 and R2, and also add these devices after creating the device group mydg.
Go to the ecc\lockbox directory verify that the repository.lb file is greater than 0kb prefbly 3kb. Options are 'oltp', which is small blocks IO, 'oltp_rep' which is oltp with replication, 'dss', which is large blocks IO, 'dss_rep' which is dss with replication and 'none' which is the set heterogeneous sets or clears heterogeneous host inform with distinctive attributes rename changes the AWWN for the specified WWN in the database and login history table refresh causes the symmetrix system The setup for host connection if the OS is Open Systems or Mainframe environments using FICON, ESCON, GbE, FC, RF, etc is all defined in the BIN file.
When running inq or syminq, you'll see a column titled Ser Num. symdisk symdisk -sid 1234 list -hotspare : Lists the Hotpsraes configured in the array. Where to get EMCgrab from? It can be set by the EMC CE, EMC ControlCenter (ECC), the Symmetrix Management Console (SMC), Solutions Enabler (SE) or essentially anyone or any application authorized to make configuration changes to
Then run a "bootadm update-archive" command to avoid the issue at the next reboot. symtier -sid 123 create -name TSDP1 -inc_type static -tgt_raid5 -tgt_prot 3+1 -technology SATA -dsk_grp 2 This command will create a flash disk tier in RAID1 format. -vp means this tier will Going forward with DMX3/4 & V-Max platforms it uses sys calls to perform these Optimizer changes). . I do not take credit for the tips mentioned below.
See the PAV section for details. http://www.sanspire.com/emc-notes-for-day-to-day-operation/ Check with the powermt_display_dev=all command to see if all the devices now have Pseudo Names. Back in the day All and any BIN file changes on the Symmetrix 3.0, Symmetrix 4.0 used to be performed by EMC from the Service Processor. I thought I could get a quick response here and hence I am posting it here as well. 2983Views Tags: none (add) support Content tagged with support , symmetrix Content tagged
symdev -sid 1234 list -hotspare : Checks whether hotspare invoked in the array . http://deftmag.com/the-configuration/the-configuration-value-could-not-be-retrieved.html Problem with ECC - Gaps in stats This happens because of repository.lb file getting corrupt. If the customer is looking at adding 32GB’s of Cache to the existing DMX-4 system or adding new Front End connectivity or upgrading 1200 drive system to 1920 drives, all these Also this is know as LUN masking.
On completion, the database device cannot be written to by the operating system.Note: This command only needs to be run once otherwise all SAN configuration is lost backup backups up No problem with renaming it and then re-doing a symcfg discover to recreate it) /var/symapi/config/netcnfg - lists the network services available from that host /var/symapi/config/options - the options file contains behavior o From FTP: (AIX, HP-UX, Linux, Solaris, Tru64) ftp://ftp.emc.com/pub/emcgrab/Unix o For OpenVMS: ftp://ftp.emc.com/pub/emcgrab/vms o For ESX: ftp://ftp.emc.com/pub/emcgrab/ESX o For ESXi: ftp://ftp.emc.com/pub/emcgrab/ESXi Control and Log files locations /usr/emc/ECC/data/swdata/symmWin.passwd - ECC Passwords are this content On client, connect to DC1_SERVER or DC2_SERVER by exporting following variables (can be done either manually or via profile files) # export SYMCLI_CONNECT_TYPE=REMOTE # export SYMCLI_CONNECT=DC1_SERVER Errors while running the commands
If you just wanted to list DiskGroups or Virtual Pools you would add the switch -dp or -vp as appropriate. Navigate to /usr/symcli/bin and run; symcfg discover symcfg list The first command gets information from the DMX and uses it to build a configuration database on your host. y The configuration change session has been aborted.
It is created based on customer specifications and installed by EMC during the initial setup. . Options are Diamond, Platinum, Gold, Silver, and Bronze, and also the default, Optimized, which has no explicit response time target associated with it. The command/CLI/API interfaces invoke system calls to effect changes, and once verified the changes are then written to the BIN file for use if the system ever needs to be rebooted. The second command lists that information out.
One BIN file per system serial number is required. . prepare another vplex metro vpool 3. symdev symdev -sid 1234 list : Lists all devices in symmetrix 1234. http://deftmag.com/the-configuration/the-configuration-could-not-be-loaded.html The first command will add 4 aliases to a specific symm.
This process of refresh is called IML (Initial Memory Load) and the BIN file is typically called IMPL (Initial Memory Program Load) file. symdev -sid 1234 write_disable ABC -SA all : Write disable the device ABC from through all directors. Request to attach VPLEX mirror failed with status 541: java.lang.NullPointerException Error 12000: An error occurred while executing the job. Administrative access can even be restricted to a specific set of volumes/devices via this mechanism.
Ideally keep it 1:1 to avoid difficulties in troubleshooting performance related issues.

Re: How to release Configuration lock Stefano Del Corno Aug 7, 2008 12:09 PM (in response to JerryRTS2) Oh yes ..
With V-Max, only a small number of back-end (DA) configuration changes remain that operate in the "old" manner you describe, and most of these will be eliminated with upcoming Enginuity updates. On client, edit /var/symapi/config/netcnfg on local Unix server (client) to define remote management servers. while a change was in progress then the symm. If there are, remove them.
From what I know, Hitachi uses a dynamic reference table in the shared memory unlike a static one described here. Gatekeepers are used to communicate with the VMAX. PowerPath Pseudo names for newly presented devices are missing upon reboot. Good point !!!
