Check the device files after the server reboots.
• Example
The following example shows the device files when a 2-drive model LT20 S2/LT40 S2/LT60 S2 is connected
to a server (with only internal DAT devices installed) that is not connected to any other tape libraries.
In this example, "0xxx" are device files for the internal DAT devices and "1xxx" and "2xxx" are device files
for the drives in the LT20 S2/LT40 S2/LT60 S2.
3.1.4 File System Performance Tuning
UFS performance may be reduced in an environment that uses ZFS.
If performance is reduced, set an appropriate value for the "zfs_arc_max" parameter in order to increase the
performance.
Refer to "Oracle Solaris ZFS Tunable Parameters" in "Oracle Solaris Tunable Parameters Reference Manual" for
details.
