Hi all,
I am setting up an ADIC Scalar i2000 library on AIX 5.2. AIX sees the
drives, but recognizes them as Other FC SCSI Tape Drive instead of LTO-2. It
did recognize them as LTO-2 with the Atape driver, but the driver did not
allow the changer to be seen. So, I am running without Atape. My question is
how to tell if the LTO-2 drives are set to use compression. I have
configured Legato NetWorker to use /dev/rmt0.1 and can access the drives and
read tape fine, but both density settings are 0 which means it should use
the drive's default setting. Is compression the default? Here is what smit
shows:
Tape Drive rmt0
Tape Drive type ost
Tape Drive interface fcp
Description Other FC SCSI Tape Dr>
Status Available
Location 1j-08-01
Parent adapter fscsi0
Connection address 1
BLOCK size (0=variable length) [0]
+
Use DEVICE BUFFERS during writes yes
+
RETURN error on tape change or reset no
+
Use EXTENDED file marks yes
+
RESERVE/RELEASE support no
+
BLOCK SIZE for variable length support [0]
+#
DENSITY setting #1 [0]
+#
DENSITY setting #2 [0]
+#
Set delay after a FAILED command [45]
+#
Set timeout for the READ or WRITE command [144]
