Hi all,
this time I'd need a help from an advanced Solaris system admin
I attached a HP StorageWorks Ultrium 215 Tape Drives - Overview - c00059530 - HP Business Support Center to my Sun E220R and it got recognized immediately (probe-scsi-all).
Now the operating system boot process finished, I logged in with root and in dmesg I can see the drive:
Here are the questions:
How can I read the tape content?
How can I eject it with a shell command?
Can I load an already ejected tape?
Do I neccessarily need a proper/commercial Backup Software?
Can't I simply do the backup using dd command?
How would I do a full backup of the main harddisk sd0 ?
How would I do a full restore of the main harddisk sd0 ?

Please also note this is 100% my personal hobbyist problem!
It's definately not a real-world problem and of course this is not a homework or something.

I'm researching a tape drive + backup software to work across my unix/linux network. Was thinking about a dds4 tape drive (sony's) on my solaris ultra2, with some kind of software that would work across the network to back up my other 2 solaris boxes, plus my 2 linux boxes. What do others use... (3 Replies)
Hi all, please help I am stuck.
I have installed a external unipack scsi tape drive. The tape drive is Exabyte Eliant 820. All I did was connected scsi cable and power it on. When issued "probe-scsi-all" command, the tape is correctly identified. However, when issued "dmesg | more" command, the... (4 Replies)
hi-
I just installed a quad gigaswift ethernet scsi card to my sunblade 150. I checked with the docs, and got all of the required drivers on the box. Now, I'm trying to mount an external scsi tape drive with no luck. I set the scsi address on the external drive to 0. Here's what I'm coming... (9 Replies)
Currenty running SCO Openserver 6 at a Dell PowerEdge T300. I recently installed a driver for an Adaptec SCSI card (adpu320).

I have 2 servers in my office which are p570 and p550. Both run under AIX 5300-07. And I only have 1 x SCSI Ultrium LTO3 Tape Drive. For syncronization purposes, I always backup p570 server's database and restore into p550 server.
And due to the frequent process of syncronization, I require to... (1 Reply)
I've had a scsi hard drive, scsi tape drive, and cd rom working off an adaptec 29160 controller. Everything worked great until a few days ago.

st_ats_enable - determine whether to reserve a tape device on open
VALUES

DESCRIPTION
Note: this tunable was named in releases prior to HP-UX 11i v3.
This tunable notifies the stape or estape driver whether it needs to reserve a tape device on open and subsequently release it on close.
When this tunable is on, the stape or estape driver will attempt to reserve any tape device on open. The driver has a few tape devices
flagged as suitable devices for this functionality including: DLT 8000, DLT 7000, STK 9840, HP Ultrium, and others. DDS drives are not
flagged for this functionality.
The tunable allows the safe sharing of tape devices in multinode configurations like MC/ServiceGuard's Advanced Tape Sharing. The auto-
matic reserve and release protects the tape device from being accessed from multiple nodes, which would corrupt a backup. If the reserve
portion of the stape or estape driver's open routine fails, a status of is returned.
Who Is Expected to Change This Tunable?
Anyone.
Restrictions on Changing
Changes to this tunable take effect immediately and are used during the next open or close.
When Should the Tunable Be Turned On?
This tunable should be turned on if the system is going to be used in an MC/ServiceGuard's Advanced Tape Sharing configuration or the user
wants the stape or estape driver to use automatic reserve and release on open and close for multinode manageability.
What Are the Side Effects of Turning the Tunable On?
A reserve is sent to the tape device by the stape or estape driver on open and a release is sent on close. No other initiator or HBA will
be able to access the tape device while it is opened on another initiator or HBA.
When Should the Tunable Be Turned Off?
This tunable should be turned off for any SAN tape sharing solution configuration other than ATS. Most multinode backup applications (for
example, Omniback) manage device reservation themselves, and any interference by the stape or estape driver may produce problems. This
tunable should also be turned off for any multiplatform SAN configuration to keep tape access across platforms more uniform.
What Are the Side Effects of Turning the Tunable Off?
Unauthorized access from another initiator might interfere with any current tape operation.
What Other Tunables Should Be Changed at the Same Time?
None.
