Troubleshoot Log Storage and Connection Issues
Step 4 Prepare the disks for migration.
Generating the metadata for each
disk pair rebuilds the indexes.
Therefore, depending on the data
size, this process can take a long
time to complete. To expedite the
process, you can launch multiple
CLI sessions and run the metadata
regeneration command in each
session to complete the process
simultaneously for every pair. For
details, see Regenerate Metadata
for M‐Series Appliance RAID Pairs.
1. Insert the disks into the new Log Collector. For details, refer to
the disk replacement procedure in the M‐100 or M‐500
Appliance Hardware Reference Guide.
The disk carriers of the M‐100 appliance are
incompatible with those of the M‐500 appliance.
Therefore, when migrating between these hardware
models, you must unscrew each disk from its old carrier
and insert the disk in the new carrier before inserting
the disk in the new appliance.
You must maintain the disk pair association. Although
you can place a disk pair from slot A1/A2 on the old
appliance into slot B1/B2 on the new appliance, you
must keep the disks together in the same slot;
otherwise, Panorama might not restore the data
2. Enable the disk pairs by running the following CLI command
for each pair:
request system raid add <slot> force no‐format
request system raid add A1 force no‐format
request system raid add A2 force no‐format
arguments are required. The
argument associates the disk pair with the new Log Collector.
argument prevents reformatting of the drives
and retains the logs stored on the disks.
3. Generate the metadata for each disk pair.
request metadata‐regenerate slot <slot_number>
request metadata‐regenerate slot 1
Step 5 Migrate the logs.
You must use the Panorama CLI
for this step, not the web interface.
You must assign the new Log
Collector to the Collector Group
that contains the old Log Collector.
1. Assign the new Log Collector to the Collector Group and
commit your changes to Panorama.
set log‐collector‐group <collector_group_name>
logfwd‐setting collectors <new_LC_serial_number>
2. For each disk pair, migrate the logs from the old Log Collector
to the new Log Collector and attach the disk pair to the new
request log‐migration from <old_LC_serial_number>
old‐disk‐pair <log_disk_pair> to <new_LC_serial_number>
request log‐migration from 003001000010 old‐disk‐pair A to
00300100038 new‐disk‐pair A
