Description: How to turn off reserve/release in solaris st device driver for hp drives
To allow solaris sharing drive in SAN environment, the ST_NO_RESERVE_RELEASE bit (0x20000) needs to be on for the tape drive, to accomplish this, do the following:
1. Modify the /kernel/drv/st.conf file, so the first part of the file looks like:
tape-config-list=
"COMPAQ SuperDLT1", "Compaq SuperDLT", "SDLT-data",
"COMPAQ SDLT320", "Compaq SuperDLT 2", "SDLT320-data",
"HP SDLT600", "HP SDLT600", "SDLT600",
"HP Ultrium 3", "HP Ultrium LTO 3", "LTO3-data",
"HP Ultrium 2-SCSI","HP Ultrium LTO 2", "LTO-data",
"HP Ultrium 1-SCSI","HP Ultrium LTO 1", "ULTRIUM";
SDLT-data = 1,0x38,0,0x39639,4,0x90,0x91,0x90,0x91,3;
SDLT320-data = 1,0x36,0,0x39639,4,0x92,0x93,0x92,0x93,3;
SDLT600 = 2,0x38,0,0x38619,4,0x4a,0x4a,0x4a,0x4a,3,0,3600,240,21600,960,960,21600;
ULTRIUM = 1,0x36,0,0x29639,4,0x00,0x00,0x00,0x40,3;
LTO-data = 1,0x3b,0,0x29639,4,0x00,0x00,0x00,0x42,3;
LTO3-data = 2,0x3b,0,0x38659,4,0x44,0x44,0x44,0x44,3,60,1200,600,1200,600,600,18000;
2. reboot the host with "-r" option, so that device drivers are recreated.
This should now be turned off.
