Hi,
I define 2 new LV on the vio server and run a cfgmgr on the partition and see my 2 new hdisk (hdisk6 and hdisk7).
I extend my vg vg000 (on the partition) and add the 2 hdisks.
I had a filesystem on the vg000 and when I added the disk I would like to increase the filesystem. But I cannot do a... (0 Replies)
We are considering a DR strategy of booting AIX 5.3 and 5.3 logical partitions from EMC Symmetrix SAN disks, so that we can replicate via SRDF to a recovery site. Has anyone tried configuring AIX 5.x systems to boot from SAN disk? If so, can you provide any information on the pros and cons of... (6 Replies)
We have a frame the uses 2 vios that assign disk storage to LPAR's. We have a LPAr with multiple disk and I want to know how do I tell which vio is serving the disk. For example the LPAr has hdisk 0, 1, 2, 3 all the same size. I want to know which vio is serving hdisk0, 1. (4 Replies)

Hello all,
I need help for erasing IBM P5 machine running AIX 5.3.
I have 2 system disks (Hardware mirror) and i'm looking for a way like a LIVE CD bootable CD so I can boot with the cd and then format the system disks with a "secure erase" software. (7 Replies)
Hi
In the vio server when I do # lsattr -El hdisk*, I get a PVID. The same PVID is also seen when I put the lspv command on the vio client partition. This way Im able to confirm the lun using the PVID.
Similarly how does the vio client partition gets the virtual ethernet scsi client adapter... (1 Reply)
Hello AIX GURU's
Can anybody tell me the steps to crate shared VG (enhanced concurent) for my Lpars from VIO server?
my questions are:
1.
Should I crate Enhanced Concurent VG in VIO and map it using virtual Scsi to Lpar?
or
2. Can I just create virtual SCSI in VIO and map to Lpar and... (1 Reply)
Hello,
I try to access to data after connect a new disk (hdisk1) to a AIX 7.1 system
This new disk was assigned to a rootvg from another AIX 6.1 system.
It seem not assigned to any vg
but if I tried to assigned hdisk1 to rootvg i get :
Data seem to be always here ... ouf ;-)... (4 Replies)

vxdarestore
vxdarestore(1M)vxdarestore(1M)NAME
vxdarestore - restore simple or nopriv disk access records
SYNOPSIS
/etc/vx/bin/vxdarestore
DESCRIPTION
The vxdarestore utility is used to restore persistent simple or nopriv disk access (da) records that have failed due to changing the naming
scheme used by vxconfigd from c#t#d#-based to enclosure-based.
The use of vxdarestore is required if you use the vxdiskadm command to change from the c#t#d#-based to the enclosure-based naming scheme.
As a result, some existing persistent simple or nopriv disks go into the "error" state and the VxVM objects on those disks fail.
vxdarestore may be used to restore the disk access records that have failed. The utility also recovers the VxVM objects on the failed disk
access records.
Note: vxdarestore may only be run when vxconfigd is using the enclosure-based naming scheme.
Note: You can use the command vxdisk list da_name to discover whether a disk access record is persistent. The record is non-persistent if
the flags field includes the flag autoconfig; otherwise it is persistent.
The following sections describe how to use the vxdarestore utility under various conditions.
Persistent Simple/Nopriv Disks in the rootdg Disk Group
If all persistent simple or nopriv disks in the rootdg disk group go into the "error" state, use the following procedure:
1. Use the vxdiskadm command to change back to the c#t#d# based naming scheme.
2. Either shut down and reboot the host, or run the following command:
vxconfigd -kr reset
3. If you want to use the enclosure-based naming scheme, add a non-persistent simple disk to the rootdg disk group, use vxdiskadm to
change to the enclosure-based naming scheme, and then run vxdarestore.
Note: If not all the disks in rootdg go into the error state, simply running vxdarestore restores those disks in the error state and the
objects that that they contain.
Persistent Simple/Nopriv Disks in Disk Groups other than rootdg
If all disk access records in an imported disk group consist only of persistent simple and/or nopriv disks, the disk group is put in the
"online dgdisabled" state after changing to the enclosure-based naming scheme. For such disk groups, perform the following steps:
1. Deport the disk group using the following command:
vxdg deport diskgroup
2. Run the vxdarestore command.
3. Re-import the disk group using the following command:
vxdg import diskgroup
NOTES
Use of the vxdarestore command is not required in the following cases:
o If there are no persistent simple or nopriv disk access records on an HP-UX host.
o If all devices on which simple or nopriv disks are present are not automatically configurable by VxVM. For example, third-party
drivers export devices that are not automatically configured by VxVM. VxVM objects on simple/nopriv disks created from such disks
are not affected by switching to the enclosure based naming scheme.
The vxdarestore command does not handle the following cases:
o If the enclosure-based naming scheme is in use and the vxdmpadm command is used to change the name of an enclosure, the disk access
names of all devices in that enclosure are also changed. As a result, any persistent simple/nopriv disks in the enclosure are put
into the "error" state, and VxVM objects configured on those disks fail.
o If the enclosure-based naming scheme is in use and the system is rebooted after making hardware configuration changes to the host.
This may change the disk access names and cause some persistent simple/nopriv disks to be put into the "error" state.
o If the enclosure-based naming scheme is in use, the device discovery layer claims some disks under the JBOD category, and the vxdd-
ladm rmjbod command is used to remove remove support for the JBOD category for disks from a particular vendor. As a result of the
consequent name change, disks with persistent disk access records are put into the "error" state, and VxVM objects configured on
those disks fail.
EXIT CODES
A zero exit status is returned if the operation is successful or if no actions were necessary. An exit status of 1 is returned if vxdare-
store is run while vxconfigd is using the c#t#d# naming scheme. An exit status of 2 is returned if vxconfigd is not running.
