57546 sysmgr unable to start
up after panic,
repeated panics
sysmgr does not start after system or sysmgr restart
after the following:
 Running setvv –snp_cpg “”
 Followed by removing the cpg which was being
used as a snap cpg before running the above
command.
 Removal of the CPG may happen a few days after.
This problem is present in all versions of InForm
2.3.1. InServs with ESX clusters attached to them will
have virtual host failures as SCSI 2 reservations will
not be handled while sysmgr is down.

When a group SS creation request is issued, sysmgr
installs VVblock on all participating parent VVs in
kernel. The callback for each SS creation in sysmgr
nullifies VVblock information for parent VV and
this parent VV is now available for participating in
another SS or group SS creation request. If sysmgr
issues multiple VVblock requests for same parent
VV, kernel VVblock IOCTL codepath will assert
seeing inconsistency. The fix is to NOT nullify
VVblock information for participating parent VV
until ref count for VVblock in sysmgr decrements to
zero.
