Subject Re: SSVM's are NOT RUNNING !
Date Tue, 29 Apr 2014 12:10:42 GMT
hi guys,

finally this issue got cleared :)

it was the problem with my xen server which had a *Stale NFS file handle.*

*found that **copy_vhd_from_secondarystorage.sh was an old file which was
used for 4.2, hence the size was going null so had to replace it.*

had to modify the *copy_vhd_from_secondarystorage.sh *to throw the
exception in *SMlog.*
