Summary

In this chapter, we’ve examined how to use various commands to determine the status of devices (particularly disk devices) that are attached to the system. In addition, we looked at how to match up Solaris logical device names to physical device references, which can be difficult for newcomers.

Questions

2.	Which of the following is a valid “available device” selection for the format command? c1t3d0 <<SUN2.1G cyl 2733 alt 2 hd 19 sec 80>> /pci@1f,0/pci@1/scsi@1/sd@3,0 /pci@1f,0/pci@1/scsi@1/sd@3,0 <<SUN2.1G cyl 2733 alt 2 hd 19 sec 80>> c1t3d0 <</pci@1f,0/pci@1/scsi@1/sd@3,0>>
3.	The /etc/path_to_inst file contains what? A list of all physical device names A list of all installed device drivers A list of mappings between device drivers and their filenames A list of mappings between physical devices and instance names
4.	What error message might be displayed if a hardware device was not installed, but the kernel loaded its device driver? May 15 14:23:16 hostname genunix: [ID 723599 kern.warning] WARNING: Driver alias “name” conflicts with an existing driver name or alias. May 15 14:26:38 hostname smt: [ID 272566 kern.notice] device is not active (conflicts with an existing driver name or alias). Initialization of this driver cannot be completed. May 15 14:26:38 hostname smt: [ID 272566 kern.notice] device is not active. Initialization of this driver cannot be completed. May 15 14:26:38 hostname smt: [ID 272566 kern.info] device is not active. Initialization of this driver cannot be completed.
5.	What does prtconf not display? System peripherals (software nodes) System architecture type Physical memory installed Virtual memory installed
6.	What command would be used to create a loopback file system on /dev/rlofi/2? newfs /dev/rlofi/2 createfs /dev/rlofi/2 format /dev/rlofi/2 lofiadm /dev/rlofi/2
7.	What command would be used to create a MS-DOS file system on a floppy disk? mkfs -F dos /dev/rdiskette mkfs -F pcfs /dev/rdiskette mkfs -F pcfs /dev/dsk/floppy mkfs -F dos /dev/dsk/floppy
8.	What command would be used to create a new file /tmp/newfile with a 2G capacity? newfile 2g /tmp/newfile mkfile 2g /tmp/newfile makefile 2g /tmp/newfile newfs 2g /tmp/newfile
9.	What command creates a new FAT file system? mkfs_dos mkfs_fat mkfs_pcfs mkfs_cifs
10.	Which of the following statements is true? tunefs tunes for both "time" and "space" tunefs tunes for "time" only tunefs tunes for "space" only tunefs tunes for "space" or "time"

Answers

1.	A. Only /pci@1f,0/pci@1,1/ide@3/dad@0,0 is a valid IDE drive name.
2.	A. Available device descriptions contain the disk name and label (c1t3d0 <<SUN2.1G cyl 2733 alt 2 hd 19 sec 80).
3.	D. The path_to_inst file contains a list of mappings between physical devices and instance names.
4.	C. Only “hostname smt: [ID 272566 kern.notice] device is not active. Initialization of this driver cannot be completed.” is valid.
5.	D. prtconf does not query virtual memory.
6.	A. newfs is always used to create file systems in this context.
7.	B. pcfs is the file system type and /dev/rdiskette is the floppy device.
8.	B. The mkfile command is used to make files of a specified capacity.
9.	C. The mkfs_pcfs command is valid in this context.
10.	D. The tunefs command must optimize for either speed or time.
