6.1 HP IBRIX X9000 Network Storage System File System User Guide (TA768-96061, June 2012)

Meta hash: 80f68a53bb4a49d0ca19af1dec18e2ff0cf965da
Data hash: d64492d19786dddf50b5a7c3bebd3fc8930fc493
The showvms command displays the hash sums stored for the file. For example:
# /usr/local/ibrix/sbin/showvms rhnplugin.py
VMSQuery returned 0
Path hash: f4b82f4da9026ba4aa030288185344db46ffda7b
Meta hash: 80f68a53bb4a49d0ca19af1dec18e2ff0cf965da
Data hash: d64492d19786dddf50b5a7c3bebd3fc8930fc493
last attempt: Wed Dec 31 17:00:00 1969
last success: Wed Dec 31 17:00:00 1969
changed: 0
In this example, the hash sums match and there are no inconsistencies. The 1969 dates appearing
in the showvms output mean than the file had not yet been validated.
Handling validation scan errors
When a validation scan detects files having hash values inconsistent with their original values, it
displays an alert in the events section of the GUI. However, the alert lists only the first inconsistent
file detected. It is important to check the validation summary report to identify all inconsistent files
that were flagged during the scan.
To replace an inconsistent file, follow these steps:
1. Obtain a good version of the file from a backup or a remote replication.
2. If the file is retained, remove the retention period for the file, using the GUI or the
ibrix_reten_adm -c command.
3. Delete the file administratively using the GUI or the ibrix_reten_adm -d command.
4. Copy the good version of the file to the data-retained file system or directory. If you recover
the file using an NDMP backup application, the proper retention expiration period is applied
from the backup copy of the file. If you copy the file another way, you will need to set the
atime and read-only status.
Creating data retention reports
Three reports are available: data retention, utilization, and validation. The reports can show results
either for the entire file system or for individual tiers. To generate a tiered report, the file system
must include at least one tier.
You can display reports as PDFs, CSV (CLI only), or in html format (GUI only). The latest files in
each format are saved in /usr/local/ibrix/reports/output/<report type>/.
When you generate a report, the system creates a CSV file containing the data for the report. The
latest CSV file is also stored in /usr/local/ibrix/reports/output/<report type>/.
NOTE: Older report files are not saved. If you need to keep report files, save them in another
location before you generate new reports.
The data retention report lists ranges of retention periods and specifies the number of files in each
range. The Number of Files reported on the graph scales automatically and is reported as individual
files, thousands of files, or millions of files. The following example shows a data retention report
for an entire file system.
