Are you running a simple TSMv6 Library Manager (LM) service?
I am trying to configure a minimal TSMv6.2 LM service and wondering,
what are minimal workable TSMv6.2 DB, Log, and Archlog allocations?
We're running an active TSMv5.5 LM service under AIX6.1 for some years now
using <1GB each for DB and Log space! [See further below, if interested]
I thought these allocations were reasonably generous for TSMv6.2 migration:
DB01 = 2GB
DB02 = 2GB
Log = 4GB [Active Log]
Archlog = 8GB [Archive Log]
but apparently Active Log space is insufficient; DSMSERV LOADFORMAT fails w/
ANR0370E rdbicbck.c(772) During the format operation, the server cannot create
files in one or more directories that you specified for ACTIVELOGDIR. Ensure
that the file system where the directory is located has sufficient space.
TSMv6.2: Planning to install server: Capacity planning: Active log space:
http://publib.boulder.ibm.com/infocenter/tsminfo/v6r2/topic/com.ibm.itsm.srv.install.doc/c_srv_inst_active_log_space.html
says:
...
The default size of the active log is 16,384 MB (16 GB). Under normal server
operations, you are likely to need an active log that is larger than the
default. The maximum size of the active log is 131,072 MB (128 GB). The minimum
size of the active log
is 2048 MB (2 GB).
...
But, that 2GB minimum size seems to be unworkable w/ TSMv6.2:
TSMv6.2: ANR Messages: Help for ANR0370E:
http://publib.boulder.ibm.com/infocenter/tsminfo/v6r2/topic/com.ibm.itsm.msgs.server.doc/msgs_server336.html
says:
...
* Check that space is available to the directories that you specified for
ACTIVELOGDIR,ARCHIVELOGDIR, and ARCHFAILOVERLOGDIR. Ensure that the amount of
space meets requirements. For example, the directory for ACTIVELOGDIR must have
at least 8 GB space available.
...
Increasing Active Log allocation >8GB, the error goes away,
so the ANR0370E message advice is apparently correct!
So...
How would you configure DB, Log, ArchLog space for this TSMv6.2 LM service?
Here's what our TSMv5.5.5 LM Service looks like:
[Our LM TSM shares 3 tape libraries w/ 16*LTO2 + 60*LTO3 + 16*LTO5 drives
w/ seven active Library Client TSM Backup/Recovery services,
and also runs a gaggle of weeknightly differential NDMP backups and
weekend DR+full NDMP backups for Oracle DBs and VMware guests on NetApps.]
