We have a Unix system with two hard drives. When we tried to access it this morning it had frozen, and when we rebooted it couldn't find one of the hard drives, and had quite a few bad data blocks on the other. Of course we fear the worst: that the drive is completely gone, but were not sure how... (1 Reply)
I need some expert help, and would appreciate any feedback on the following problem:
After power outage the machine didn't allow the login. When we checked it , it looked like both disks were completely empty. Luckily, we have a backup machine, and we can restore the disks.
Has anybody seen... (3 Replies)
Hi, First post. I am not to experienced in the Unix or HP-UX world but I'm learning.
We have some problem with a HP rx4640 server. During boot it states the following:

Volume group "/dev/vg00" has been successfully changed.

Hi all,
we have an existing system that was configured using just one of the (two) internal disks. I want to mirror the disk using SVM, but have realised there is no free slice for creating the metadb's. Is there a workaround I can use for this?
In the past we have always kept slice 7 free -... (8 Replies)

Hi everyone
I have a problem. My configuration is as follows:
Sun 280R server
2 x internal disks
3 x state databases on disk 1
3 x state databases on disk 2
Disk 1 was giving errors, so I cleared the mirrors on it, deleted the state databases and replaced the disk. Before attaching... (5 Replies)
Hi Solaris 10 Experts,
I am wondering what is the correct syntax to edit in Grub when trying to specify the local ZFS boot disk while booting up from a Solaris 10 x86 64bits DVD installation disk. In other word, I try to boot up from local disk without removing the Solaris installation disk... (0 Replies)
Hi,
I'm looking to copy a boot disk on an old Solaris 8 system using dd. I'll bring the system down to single user mode and begin from there. I'm copying my source disk to a larger target disk. Do I need to do anything other than the 'dd' command below because the target disk is bigger? ... (2 Replies)
mddb.cf(4) File Formats mddb.cf(4)NAME
mddb.cf - metadevice state database replica locations
SYNOPSIS
/etc/lvm/mddb.cf
DESCRIPTION
The /etc/lvm/mddb.cf file is created when the metadb(1M) command is invoked. You should never directly edit this file.
The file /etc/lvm/mddb.cf is used by the metainit(1M) command to find the locations of the metadevice state databases replicas. The metadb
command creates the file and updates it each time it is run. Similar information is entered in the /kernel/drv/md.conf file.
Each metadevice state database replica has a unique entry in the /etc/lvm/mddb.cf file. Each entry contains the driver and minor unit num-
bers associated with the block physical device where a replica is stored. Each entry also contains the block number of the master block,
which contains a list of all other blocks in the replica.
Entries in the /etc/lvm/mddb.cf file are of the form: driver_name minor_t daddr_t checksum where driver_name and minor_t represent the
device number of the physical device storing this replica. daddr_t is the disk block address. checksum is used to make certain the entry
has not been corrupted. A pound sign (#) introduces a comment.
EXAMPLES
Example 1 Sample File
The following example shows a mddb.cf file.
#metadevice database location file do not hand edit
#driver minor_t daddr_t device id checksum
sd 152 16 id1,sd@SSEAGATE_JDD288110MC9LH/a -2613
In the example above, the value for daddr_t indicates that the offset from the start of a given partition is 16 disk blocks from the start
of that partition.
