finding free disk at EVA

[S.S.]

Dear All,

For one of our dba filesystem has been occupied to 100% and they have asked me to extend this filesystem. I have checked that there is no free space available in the volume group to extend. We have SAN EVA8000 and may i know how can i find a free disk available at EVA to add that to the existing volume group?

You don't present disks from EVA to the server, but LUNs (vdisks).
Depending on your OS version you may consider to extend the existing vdisk or create a new vdisk in order to extend the VG on the server.

If you have storage Admin support - You can get helped or You Can check the EVA8000 storage adminstartion Console via "IE - Browser" by typing the EVA 8000 storage IP and you can Check the free disk.

Once you find the free disk, you need to create (vdisk) and present the (vdisk) LUNS to Server

than Once LUNS has been presented, you can extend the (volume group) and than increase the file system space.

Hi Johnson,

I found the free space at EVA and also found how to create the vdisk also.

After creation of vdisk, may i know the steps to Present LUNS to the server.

My OS version is HP-UX 11.11
model is rp3440.

>>I found the free space at EVA and also found how to create the vdisk also<<<

How did you manage ? Using command line ?

[S.S.]

Yes, At Comman view EVA i have found 3 disk groups. The existing vdisks of this server is pointing to one of the disk group. I have checked the total size of that disk group and i found there is free size available on this disk group.

Once i know the procedure how to present the LUNS to server then i will create a vdisk.

In command view EVA->click virtual disk->create vdisk->during vdisk creation, there is a option called "Present to host" dropdown list. In dropdown list to my server(test)i have test-fcd0 & test-fcd1.

>>called "Present to host"<<

Yes, you need present (vdisks) to host

Johnson,

In "present to host" i can select only only host say test-fcd0. If i want to select bot test-fcd0 and test-fcd1?
