fourth node in Hyper-v cluster unable to create VHDs

-

hello, 

i have added fourth node our hyper-v failover cluster , unable live migrate or create new vms in scvmm 2008 r2 sp1, failover cluster manager or hyper-v manager.

the new node has identical nic , hardware configuration , difference sp1 others not.

i have:

  • installed dell san drivers (not management utils of kind) 
  • enable vt , dep in bios , power cycled
  • configured iscsi multipath san
  • added node host group (presenting luns)
  • added node cluster

i can confirm csvs readable , writeable new node, however, can't create new vm or live migrate existing 1 it. here details of each scenario:

creating new vm

in hyper-v manager, fails error "a virtual disk support provider specified file not found". , no changes made.

in scvmm, fails @ 82% after few seconds , gives more information:

 

error (12700)

vmm cannot complete hyper-v operation on the  <host> server because of error: 'the system failed create 'c:\clusterstorage\volume2\testagain\testagain_disk_1.vhd'. error code: virtual disk support provider specified file not found. 

 (a virtual disk support provider specified file not found (0xc03a0014)) 

recommended action

resolve issue in hyper-v , try operation again.

 

the folders vm created, bootable (in hyper-v manager), no disks present

live migrating vm

this fails @ 99%, assume @ point dirty blocks of memory trying moved, following error:

 

error (10698)

virtual machine <vm> not live migrated virtual machine host <host> using cluster configuration. 

 (unspecified error (0x80004005)) 

 

recommended action

check cluster configuration , try operation again.

performing same operation in failover cluster manager says migration failed.

 

here steps i've performed while troubleshooting:

  • changed relevant fsdepends dword 0
  • configured quorum disk in fcm
  • changed "network live migration" in fcm
  • evicted node cluster, pulled off , reconfigured iscsi stuff, , re-added cluster
  • services running on old , new hosts identical

i @ loss i've missed setting up, , appreciated

thanks

hi ben,

after adding new node, did run "validate configuration" wizard entire solution?  did come clean?

does new node have same processor type , version?  if live migrating different version in same processor family, make sure have checked 'processor compatibility' option under process settings vm trying live migration.

thanks,

List Styles

in word 2010, defined new list style called “custom1′ “new docs based on template” instead of “this doc only.” heading 1, 2, 3, etc. appear linked within document. document create list style called “custom2′ , choose make available “new docs based on template” , also link them heading styles. though both list styles show available new docs, 1 of list styles (the last 1 used) linked heading styles. in word's default list library, multiple multi-level lists appear be linked heading styles. not able link heading styles multiple custom list styles? a particular list style can have 1 set of paragraph styles associated (one style each numbering level). the list formats in so-called list library behave differently, have noticed. similar predefined formats in bullets , numbering dialog box of word 97-2003. stefan blom, microsoft word mvp ...
