Where install VIOM: on Windows? or on Linux?
Hi every one: I want to install VIOM, I never do it before, and my first question is: Where I should do it? In Windows envioroment? or in Linux Envioroment? All my clusters are in Linux Envioroment: Infoscale 8.0 on Red Hat 8.9. Other question: Is it posible install Cordination Point Service in the same server? All my clusters have 2 nodos: node one in one CPD (site 1) and the node two in other CPD (site 2). I think that the new server (VIOM+CP) shultd be another CPD (site 3). Correct? Thanks Jaime.(CEP-19095) InfoScale Usage & Experience

DRL not working on mirrored volumes in VVR - RVG (Mirrored volume doing full resync of plexes)
I think I am hitting a major issue here with a mirrored volume in RVG. SRL is supposed to provide the DRL functionality . Hence DRL logging is explicitly disabled when a volume is added to RVG. However my testing shows that DRL is not working and in the case of a mirror plex out of sync due to a server crash etc, full resync of mirror plexes is happening. (not just the dirty regions). Here is a quick and easy way to recreate the issue: My configuration: Infoscale 8 Redhat 8.7 I have a mirrored volume sourcevol2 (2 plexes) which I created like below: #vxassist -g dg1 make sourcevol2 1g logtype=dco drl=on dcoversion=20ndcomirror=1 regionsz=256 init=active #vxassist -b -g dg1 mirror sourcevol2 I wait for the synchronization to complete #/opt/VRTS/bin/mkfs -t vxfs -o nomaxlink /dev/vx/rdsk/dg1/sourcevol2 # mount /dev/vx/dsk/dg1/sourcevol2 /sourcevol2 I create SRL as below: #vxassist -g dg1 make dg1_srl 1g layout=concat init=active I create primary rvg as below: #vradmin -g dg1 createpri dg1_rvg sourcevol2 dg1_srl Verified dcm in dco flag is on. #vxprint -g dg1 -VPl dg1_rvg |grep flag flags: closed primary enabled attached bulktransfer dcm_in_dco Added secondary #vradmin -g dg1 addsec dg1_rvg primarynode1 primarynode2 Started initial replication #vradmin -g dg1 -a startrep dg11_rvg primarynode2 Verified replication is uptodate #vxrlink -g dg1 -T status rlk_primarynode2_dg1_rvg VxVM VVR vxrlink INFO V-5-1-4467 Rlink rlk_primarynode2_dg1_rvg is up to date Here is the actual scenario to simulate mirror plexes out of sync : On primary: Run a DD command to put some IO on sourcevol2 #dd if=/dev/zero of=/sourcevol2/8krandomreads.0.0 bs=512 count=1000 oflag=direct In another terminal , force stop the sourcevol2 while dd is going on. #vxvol -g dg1 -f stop sourcevol2 #umount /sourcevol2 Start the sourcevol2 #vxvol -g dg1 start sourcevol2 #vxtask -g dg1 list -l Task: 160 RUNNING Type: RDWRBACK Operation: VOLSTART Vol sourcevol2 Dg dg1 Even though I only changed only few regions on the sourcevol2 (sequential writes of 512b), the volume goes through a full plex resync (as indicated by the time to start the volume). Summary: DRL on a Volume added to an RVG is not working . Hence mirrored volumes are going through a full plex resync as opposed to only resync of dirty regions.Does Infoscale Storage (VVR) support cascaded space-optimized snapshot?
Configuration: Infoscale Storage 8.0 on Linux Infoscale storage foundation supports cascaded snapshot using vxsnap infrontof= to do cascaded snapshots Infoscale storage (with Volume replicator) documentation doesn't describe cascaded snapshot. I checked manpage for vxrvg. Does not have an infront of attribute. Does that mean cascaded space-optimized snapshots are not supported/permitted on RVG?Does VVR support cascaded space-optimized snapshot?

fencing driver fail after storage firmware
In emc unity 380, fencing disk abnormal after firmware. So the b port doesn't go up. Do you have any why this is? https://sort.veritas.com/public/documents/sf/5.0/solaris64/html/sf_rac_install/sfrac_error_messages5.html Does this problem occur when the serial number of the disk is changed?
VCS Simulator 7.0
Hello all. VCS simulator has been around for quite a while and it is a really usefull tool both for testing cluster configuration files before put them in production and for DEMO purposes which is my case and that's why I'm writing this post. Is there any user guide or document explaining how to use or how are configured the included cluster configuration examples? I've been able to understand some cluster examples and use some features, but some other cluster examples seem like some configuration is required to make them work but as there's no information (to my knowledge) on how they are configured, I haven't been able to find a way to make this cluster examples work. Really appreciate any guidance that points my into the right direction.
