import-id: 0.1
flags:
copies: nconfig=default nlog=default
config: seqno=0.1171 permlen=2993 free=2987 templen=4 loglen=453
config disk dsk2 copy 1 len=2993 state=clean online
config disk dsk3 copy 1 len=2993 state=clean online
log disk dsk2 copy 1 len=453

The output from this example shows that the configuration database length is 2993. The private
region size for the disks in this example is the default size of 4096.
Additional Step Required to Recover from a Temporary Disk Failure Under LSM Control (Nov.
2003)
In Section 6.4.3 of the Logical Storage Manager manual — Recovering From Temporary Disk
Failures — there is an extra step required before recovering the volumes. You must readd the
failed disks to the affected disk group(s), using the option to restore the last-known disk media
names.
The complete process to recover from temporary disk failures includes the following steps:
1. Make sure the disk is back on line and accessible; for example:
• Confirm that the disk is firmly snapped into the bay.
• Reconnect any loose cables.
• Perform any other checks appropriate to your system.
2. Scan for all known disks to ensure the disk is available:
# voldctl enable
3. [NEW] Readd the failed disk (or disks) to the appropriate disk group(s):
# voldg -[-g diskgroup] -k adddisk \
disk_media_name=disk_access_name
For example, to readd disk dsk14 to the dg1 disk group, where the disk media name is
datadisk:
# voldg -g dg1 -k adddisk datadisk=dsk14
Or, for example, to readd disk dsk22 to the rootdg disk group, where the disk media name
and disk access name are the same:
# voldg -k adddisk dsk22=dsk22
4. Recover the volumes on the disk:
# volrecover -sb disk
AdvFS Administration Manual Correction — Extend an AdvFS File System When Increasing the
Size of the Underlying Volume (April 2003)
In Section 2.3.4.3 of the AdvFS Administration manual — Increasing Storage in Domains by
Extending an Existing Volume — there is an extra step required when the underlying storage
volume is a hardware RAID device. You must modify the volume's disk label information to
reflect the new, increased size of the partition supporting the domain, and then apply the updated
disk label to the volume before extending the file system.
The complete process to extend a domain by increasing the size of an underlying hardware RAID
volume includes the following steps:
1. Using HSG80 commands, extend the hardware RAID volume.
This might involve adding another stripeset to an existing stripeset, or creating a concatset
from the original hardware RAID volume and adding another volume to it.
