## NetApp Tips ##
SnapVault volume
typically have a much longer retention than source volumes, hence they will
need to be created larger!
Q: Quota Rule or Tracking Quotas on Volume root for Used
Space?
A: Not necessary since default volume stats will suffice.
Q: Fractional Reserve Settings on Thin Provisioned (no
space guarantee) Volumes?
A: 0%
Q: Snapshot Reserve at its most simple?
A: For simplicity, consider setting all Snapshot Reserves
to 0%, this saves having to adjust Snapshot Reserve depending on the use of
retention, also, means departmental teams will see the space used not just by
their live data, but also their retention.

Troubleshooting CIFS/Kerberos Issues on CDOT:
secd.log (security
daemon.log):
Look for Kerberos errors, also DNS and authentication
errors.
SYSVAR-NBLADE (command
output from systemshell):
Just shows counters, can look at what is incrementing to
identify issues (also sent via ASUP under "SYSCTL-SYSVAR-NBLADE")
mgwd.log (management
gateway log):
The majority of processes come here at some point, and if
there is a problem here, it may never get to a later process.
ems.log:
Catch all. Nothing specific to look for, but something
might catch your attention.
General Action Plan for Protocol Related Issues:
- ASUP
- Start Packet Trace
- Reproduce issue
- Stop Packet Trace
- ASUP
## Veeam ##
## VMware ##
This issue occurs when you expand a virtual disk vmdk
file which has Change Block Tracking (CBT) enabled past any 128GB boundary.
To work around this
issue:
After having
extended the CBT-enabled disks past a 128 GB boundary:
1. Turn off CBT.
2. Take a snapshot
(Does suspend/resume).
3. Delete the
snapshot (To recover space and performance).
4. Turn on CBT.
5. Take a snapshot
(Again with the suspend/resume).
6. Delete the
snapshot.
