What is the solution for Solaris9 SVM SUN CLUSTER EMC storage expansion? many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

First, for the purpose of expansion, the existing / zxme/nas file system space cannot meet the business needs, so the file system space needs to be expanded. Current file system status: / dev/md/zxmedg/dsk/d320 61923644 18931228 42373180 31% / zxme/nas the current file system is about 59g, which is expected to increase to about 200g. Current system information host: SUN V440 dual storage: DELL | EMC CX300 operating system: SunOS 5.9Expandable hardware: 2 146GDELL | EMC hard disk

Second, the expansion plan is divided into two parts: the first part is the storage side expansion, that is, DELL | the second part is the host side expansion, that is, adding the newly obtained space to the / zxme/nas file system to expand the storage side. Introduction: insert two new 146g hard disks in slot 10 and slot 11 of DELL | EMC CX300, and then divide it into a new RAID group, configure it as RAID1, and then configure a LUN to select the maximum (MAX) space. It is expected to be about 140g, and then assign the new LUN to the STORAGE GROUP to complete the configuration of the storage. Description of CVM capacity expansion: scan the newly added disk on the CVM to ensure that both hosts correctly identify the newly added LUN. Then stop the sun cluster service, back up the contents of the / zxme/nas file system to a WINDOWS machine, then add the new disk to the zxmedg disk set, delete the old D320 volume, regenerate the large D320 volume (including 57g disk and the new 140g hard disk), finally execute the growfs command, expand the file system, and finally mount/zxme/nas the file system to see if the data is intact and if the data is normal, start the cluster and test.

Third, expand the storage capacity of the specific content of the solution:

1. Prepare the expansion materials, 2 146GDELL | EMC hard drives, and check whether the disk pins are intact and the capacity is correct.

2. Prepare a WINDOWS host equipped with DELL | EMC storage management software and JAVA environment, and add the network card of the host to the ip address and mask of the same network segment of the management IP of the CX300 storage SP to ensure that the host can PING the IP of the storage SP.

3. Insert two 146g new hard drives in slot 10 and slot 11 of CX300 storage. When the hard disk is first inserted, the internal test of the hard disk begins (identified by the disk indicator). Wait a moment if there is nothing wrong with the disk, it will be checked.

4. Open the storage management software and use the user name and password: admin/password

5. Select CX300- > Physical- > Bus 0 Enclosure0 [DAE]-> Disks to check whether all the hard disks are normal (when there is a disk failure, there will be an X on the icon) to make sure that the disk is normal.

6. Select CX300, right-click, select Create Raid Group, open the RAID GROUP creation dialog box, select Manaual with DISK SELECTION option, click SELECT, join DISK9 and DISK10, and finally click OK to complete the creation of RAID GROUP.

7. Select CX300- > RAID GROUUP, right click the new RAID GROUP you just created, select BIND LUN, open the create LUN dialog box, select RAID1,LUN SIZE, select MAX, and finally click APPLY to complete the creation of LUN.

8. Select CX300- > STORAGEGROUUP, add the LUN you just created to LUNS, and then click OK. At this point, after the storage end is configured, the expansion of the host side is introduced:

1. Run the powermt display dev=all command to see if the host has detected the newly added LUN.

2. If the above is not detected, run the devfsadm and drvconfig commands to re-search the disk to ensure that the host correctly recognizes the hard disk.

3. Run the scdidadm-L command as root, you can see the disk managed by SUN cluster, and find out the number of DXX corresponding to the newly added disk.

4. If the DXX number of the new disk is not found in the previous step, manual MAP uses the command: scdidadm-r is executed on two machines respectively.

5. Run the scdidadm-L command again to see the disk managed by SUN cluster, and find out the number of the DXX corresponding to the newly added disk.

6. Restart the two hosts using the command: shutdown-G0-y-i6

7. Stop sun cluster to ensure that the data in the / zxme/nas file system is not used or updated using the command: scswitch-F-g zxme-harg

8, mount / zxme/nas file system manually

9, back up the data from the / zxme/nas file system to a WINDOWS server (approximately 20g of space is required)

10. Check and record the owner and group, read and write permissions of the files under / zxme/nas, so that they can be restored as is if there is a problem.

11. Mount / zxme/nas file system, namely umount / zxme/nas

12, add the newly added physical volume, such as DXX (if D17) to the zxmedg disk set, use the command: metaset-s zxmedg-a / dev/did/rdsk/d1710, use the command metastat-s zxmedg to see if D17 has successfully joined the zxmedg disk set 11, clear the old D320 logical volume use the command: metaclear-s zxmedg d32012, create a new D320 logical volume Use the command: metainit-s zxmedg d3202 1/dev/did/rdsk/d15s0 1/dev/did/rdsk/ d17s0 (new disk) (concatenate two disks)

13. Extend the file system using the command: growfs-M / zxme/nas / dev/md/zxmedg/rdsk/d320

14. Mount / zxme/nas file system manually using the command: mount / dev/md/zxmedg/rdsk/d320 / zxme/nas

15. Check whether the data of / zxme/nas file system is normal, and see whether the capacity of Ronglai is expanded cd / zxme/nas.

16, umount / zxme/nas file system after no problem

17. Start the cluster test and use the command: scswitch-Z-g zxme-harg to this host.
